On an icy (nearly frictionless) street a 600 kg car traveling straight east at 5 m/s collides with a 1000 kg car traveling straight north at 3 m/s. after the collision, the cars bounce off of each other and slide away. After the collision, the first car moves at 2 m/s straight north.
a) what is the final speed of the second car?
b) what is the direction of motion of the second car?
c) is this collision elastic?
