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?
Determine the same situation, but now let the initial speed v0 of the first ball be given and treat the height h of the building as an unknown. What should the height of the building be for both balls to reach the ground at the same time for v0= 8..
