Multiple Choice

A 250 g rubber ball bounces off a wall. As it strikes the wall, it is moving in the negative x-direction at

11 m/s

, and as it bounces off, it is moving in the positive x-direction at

10 m/s

. What is the impulse on the ball from the wall?

16 m/s

Three cars approach an intersection: an 800 kg car moves in the positive x-direction at

10 m/s

, a 1200 kg car moves in the negative x-direction at

5 m/s

, and a 900 kg car moves in the positive y-direction at

12 m/s

. What is the total momentum of this system of three cars? Give your answer as a magnitude and an angle counterclockwise from the positive x-axis.

Textbook Question

Two vehicles are approaching an intersection. One is a 2500-kg pickup traveling at 14.0 m/s from east to west (the -x-direction), and the other is a 1500-kg sedan going from south to north (the +y-direction) at 23.0 m/s. (b) What are the magnitude and direction of the net momentum?
