Chapter 6.3, Problem 8P

A vehicle with a mass of $\text{80}\bar{\text{0}}\text{ kg}$ is traveling west with a velocity of 20.0 m/s. It collides with a vehicle of the same mass that is not moving. Assume an elastic collision, the first vehicle is deflected at 30.0° north from its original path. The second vehicle’s path is 90° to the left of the first vehicle’s final path. (a) What is the momentum of the first vehicle after the crash? (b) What is momentum of the second vehicle after the crash? (c) What is the velocity of the first vehicle after the crash? (d) What is the velocity of the second vehicle after the crash?
