The Ideal Transformer. Microscopes and Telescopes. This book is intended for use by students of general physics, either in calculus- or noncalculus- based courses. Problems requiring real calculus not merely calculus notation are marked with a small superscript c. The only way to master general physics is to gain ability and sophistication in problem-solving. This book is meant to make you a master of the art - and should do so if used properly.

As a rule, a problem can be solved once you have learned the ideas behind it; sometimes these very ideas are brought into sharper focus by looking at sample problems and their solutions.

If you hav.

There are numerous ways of posing a problem and, frequently, numerous ways of solving one. You should try to gain understanding of how to approach various classes of problems, rather than memorizing particular solutions.

Understanding is better than memory for success in physics. The problems in this book cover every important topic in a typical two- or three-semester general physics sequence. Ranging from the simple to the complex, they will provide you with plenty of practice and food for thought. The Chapter Skeletons with Exams, beginning on the next page, was devised to help students with limited time gain maximum benefit from this book.

It is hoped that the use of this feature is self- evident; still, the following remarks may help: The Chapter Skeletons divide the problems in this book into three categories: Turn to page ix to see an example. To gain a quick overview of the basic ideas in a chapter, review the SCAN problems and study their printed solutions.

HOMEWORK problems are for practicing your problem-solving skills; cover the solution with an index card as you read, and try to solve, the problem. Do both sets if your course is calculus based.

Calculus-based students are urged also to take the Hard Exam. Exams run about 60 minutes, unless otherwise indicated. Still further problems constitute the two groups of Final Exams. Stay in your category ies , and good luck. Easy A A scalar quantity has only magnitude; it is a pure number, positive or negative. Scalars, being simple numbers, are added, subtracted, etc. It may have a unit after it, e. A vector quantity has both magnitude and direction. A vector quantity can be represented by an arrow drawn to scale.

The direction of the arrow represents the direction of the vector quantity. The resultant of a number of similar vectors, force vectors, for example, is that single vector which would have the same effect as all the original vectors taken together.

They may be taken in any order of succession. The tail end of each arrow is attached to the tip end of the preceding one. The resultant is represented by an arrow with its tail end at the starting point and its tip end at the tip of the last vector added. The resultant of two vectors acting at any angle may be represented by the diagonal of a parallelogram.

The two vectors are drawn as the sides of the parallelogram and the resultant is its diagonal, as shown in Fig. The direction of the resultant is away from the origin of the two vectors. Find its diameter in a millimeters, b megameters, c miles.

The runners run eastward at the start and bend south. What is the displacement of the endpoint of the race from the starting point? A component of a vector is its "shadow" perpendicular drop on an axis in a given direction. For example, the p-component of a displacement is the distance along the p axis corresponding to the given displacement. It is a scalar quantity, being positive or negative as it is positively or negatively directed along the axis in question. In Fig. One sometimes defines a vector component as a vector pointing along the axis and having the size of the scalar component.

If the scalar component is negative the vector component points in the negative direction along the axis. It is customary, and useful, to resolve a vector into components along mutually perpendicular directions rectangular components. The x component of the resultant, Rx, is the algebraic sum of all the x components. The y and z components of the resultant are found in a similar way. Choose x, y axes as shown in Fig. The resultant vector, R, points from starting point to endpoint as shown.

Measure its length on the scale diagram to find its magnitude, 4. Using a protractor, measure its angle e to be , The resultant displacement is therefore 4. I The vector displacement and its components are shown in Fig. Note in particular that each component points in the negative coordinate direction and must therefore be taken as negative.

I Resolve each vector into rectangular components as shown in Fig. Place a cross-hatch symbol on the original vector to show that it can be replaced by the sum of its vector components. Find F'x and Fy. I a Recalling that vectors can be added in any order we can immediately add the 3.

Similarly the 5. Because the east displacement contributes no component along the north-south line and the south displacement has no component along the east-west line, the car is Algebraically we note that. I Formal method uses angle above positive x axis: I Split each into components and find the resultant: Since the pulleys are frictionless and with negligible mass, the tension T in the cord is the same everywhere. The forces on the leg and foot from the device are caused by the tensions in the cord.

Assume the pulleys have negligible friction and weight. Call T the tension in the rope the man is holding; T is the same throughout the one piece of rope. The other vertical force on the man is the tension in the rope attached to the pulley above the man's head, which must be 2T for the pulley in equilibrium.

The net vertical force is 3T, which is balanced by his weight of N. Find the angle e. Why download extra books when you can get all the homework help you need in one place?

As a result, the chain supporting the lower pulley is shortened by a length 2:rcR - 2:rcr. The load w is lifted half this distance,!

The length of the rope which lands on the table during an interval dt following this instant is v dt.

The increment of momentum imparted to the table by this length in coming to rest is m v dt v.

He is coasting along the station at a speed of 1. He wishes to change his direction of motion by 90 and to increase his speed to 2.

His total mass is kg, including his spacesuit and rocket belt, which provides a thrust of 50 N. How must the rocket be pointed? How long would this take?

Initially the boat was at rest. Find the magnitude and direction of the velocity acquired by the boat. Let 1 refer to the man and 2 to the boat. Let the mass of the boy and the boxcar be M. He throws a ball of mass m with velocity Votoward the other end, where it collides elastically with the wall and travels back down the length L of the car, striking the opposite side inelastically and coming to rest. If there is no friction in the wheels of the boxcar, describe the motion of the boxcar; All forces are internal Fig.

Therefore, if V and v are the velocities of the boxcar plus boy and the 9.

US Consider the system composed of a I-kg body and a 2-kg body initially at rest at a center-to-center distance of 1 m. All numerical values quoted in this exercise are to be considered exact, and the 2-kg body is to the right of the I-kg body. What is its resultant acceleration? What would its acceleration be? The stool can turn freely on its axle.

Holding the axle vertically with one hand, she grasps the rim of the wheel with the other and spins the wheel clockwise as seen from above. What happens to the volunteer as she does this?

What happens? The instructor now hands the wheel back to the volunteer. What happens now? What is the result? Since the axle of the piano stool is frictionless, there are no vertical torques exerted on the stool-volunteer system, so the vertical component of angular momentum is conserved. There are horizontal torques; these result from forces that the floor exerts on the base of the stool.

Therefore, the volunteer spins counterclockwise. The volunteer's vertical component of angular momentum must now be zero, so she stops spinning. The volunteer remains stationary.Notice Message: The tangent lines are shown in Fig. Plus, we regularly update and improve textbook solutions based on student ratings and feedback, so you can be sure you're getting the latest information available.

Note that the force due to the atmosphere cancels on the left and right of the disk. Book Details Author: HOMEWORK problems are for practicing your problem-solving skills; cover the solution with an index card as you read, and try to solve, the problem.
