Chapter 4, Problem 1PLA

Chapter 4, Problem 1PLA, These pictures show a cart that is moving at constant velocity. (a)(b)(c)(d)

These pictures show a cart that is moving at constant velocity.

(a)    (b)    (c)    (d)

Expert Solution & Answer

To determine

The cart that is moving at constant velocity

Answer to Problem 1PLA

Option (b)

Explanation of Solution

Constant velocity specifies that the car covers equal amount of displacement in a given time duration. The carts pictured in the question are all moving in a straight line to the left. From the picture, it is evident that the cart (b) gets displaced equally for every 1.00 s.

Conclusion:

From the picture, it is evident that the cart (b) gets displaced equally for every 1.00 s. Therefore, option (b) is correct.

The displacement of cart in (a) is increasing with time, hence the cart a is not moving with constant velocity.

The displacement of cart in (c) is decreasing with time, hence the cart a is not moving with constant velocity.

The displacement of cart in (d) is not uniform, hence the cart a is not moving with constant velocity.

The juggling skateboarder is back outside my office! He starts with a speed of of 3.0 m/s at a height ten meters above lake level, and then rolls down Campus Drive. Assuming that the effects of friction were negligible, how fast should he be moving when he is just two meters above lake level?
As shown in (Figure 1), block AA (mass 2.10 kgkg) rests on a tabletop. It is connected by a horizontal cord passing over a light, frictionless pulley to a hanging block BB (mass 1.28 kgkg). The coefficient of kinetic friction between block AA and the tabletop is 0.353. The blocks are released then from rest.   Find the speed of each block after moving 3.20 cm. Find the tension in the cord.
