2-A 10.0 Kg block is released from point A in the figure below. The block travels along a smooth frictionless track except for the rough 1 m long portion between points B and C. It makes a collision with stationary 10 kg ball after passing point C. The ball moves forward with speed of 2 m/s.
a) What is the speed of the block at point C?
b) What is the velocity of the block after the collision?
c) Does the block return back to the inclined? If It does how high does it get on the incline?
d) Determine whether the collision was elastic or inelastic
