Chapter 5: Q.18 (page 128)

Exercises 18 show two of the three forces acting on an object in equilibrium. Redraw the diagram, showing all three forces. Label the third force F3鈫�.

Short Answer

Expert verified

The net force of F3鈫�should be acting on the object such that the object is at equilibrium.

Step by step solution

01

Given information:

From the given diagram, one can observe thatF1>F2.

02

Draw the force diagram with net force:

The net force acting on the given diagram is

F=F1 + F2

Since both the forces are in opposite directions, the net force will be reduced and acting along F1.

It can be seen from the below force diagram:

03

Draw the force diagram for F3:

Since the net force is along F1, the third force F3 should act in such a direction to nullify the net force F.

Therefore, the F3 must be acting along F2 as shown in the below force diagram:

If a car stops suddenly, you feel 鈥渢hrown forward.鈥� We鈥檇 like to understand what happens to the passengers as a car stops. Imagine yourself sitting on a very slippery bench inside a car. This bench has no friction, no seat back, and there鈥檚 nothing for you to hold onto. a. Draw a picture and identify all of the forces acting on you as the car travels at a perfectly steady speed on level ground. b. Draw your free-body diagram. Is there a net force on you? If so, in which direction? c. Repeat parts a and b with the car slowing down. d. Describe what happens to you as the car slows down. e. Use Newton鈥檚 laws to explain why you seem to be 鈥渢hrown forward鈥� as the car stops. Is there really a force pushing you forward? f. Suppose now that the bench is not slippery. As the car slows down, you stay on the bench and don鈥檛 slide off. What force is responsible for your deceleration? In which direction does this force point? Include a free-body diagram as part of your answer.

A constant force applied to A causes A to accelerate at 5m/s2 . The same force applied to B causes an acceleration of 3m/s2 . Applied to C, it causes an acceleration of 8m/s2.

a. Which object has the largest mass? Explain.

b. Which object has the smallest mass?

c. What is the ratio mAmBof the mass of A to the mass of B?

Suppose you press your physics book against a wall hard enough to keep it from moving. Does the friction force on the book point

(a) into the wall,

(b) out of the wall,

(c) up,

(d) down, or

(e) is there no friction force? Explain.

For an object starting from rest and accelerating with constant acceleration, distance traveled is proportional to the square of the time. If an object travels 2.0 furlongs in the first 2.0 s, how far will it travel in the first 4.0 s?
