Chapter 7, Problem 16E
A 4150-kg truck traveling with a velocity of 12 m/s due east collides head-on with a speeding 900-kg car traveling with a velocity of 40 m/s due west. The two vehicles stick together after the collision.
- a. What is the momentum of each vehicle prior to the collision?
- b. What are the size and direction of the total momentum of the two vehicles after they collide?
