Chapter 4, Problem 2FTD

A ball bounces off a wall with the same speed it had before it hit the wall. Has its momentum changed? Has a force acted on the ball? Has a force acted on the wall? Relate your answers to New-ton’s laws of motion.

During a collision with a wall, the velocity of a 0.200-kg ball changes from 20.0 m/s toward the wall to 12.0 m/s away from the wall. If the time the ball was in contact with the wall was 60.0 ms, what was the magnitude of the average force applied to the ball? O 167N 0400N O 13.3 N 107 N

Q8. In Figure Q8, the motor B is moving the crate A upward at a constant velocity of v = 4.5 m/s. The coefficient of kinetic friction between the crate A and the inclined surface is a = 0.2. Suddenly, the cable fails and the crate A slide downward. (a) Draw the free body diagram of the crate A at BOTH moving upward and sliding downward. (b) Using principle of impulse and momentum, determine the speed of the crate A at 2 seconds after the cable failed. Motor B 4.5 m/s Crate A FIGURE Q8
