Physics

Momentum, Impulse, and Collisions:

A 1050kg sports car is moving westbound at 15.0m/s ona level road, when it collides with a 6,320kg truck driving east onthe same road at 10.0m/s. The two vehicles remain locked togetherafter the collision.

What is the velocity (magnitude & direction) ofthe two vehicles just after the collision?


At what speed should the truck have been moving sothat both it and the car are stopped in the collision?


Find the change in kinetic energy of the system of twovehicles for the situations of part a) and b). 


For which situation is the change in kinetic energygreater in magnitude?
