Answer #1

b) when it is just about to touch the spring it will have maximum velocity after which spring will compress speed of the ball will began to decrease

c)when spring is compressed with maximum at this time the ball will be at zero velocity for some time untill the spring try to restore its position by decompression and bal will regain velocity.
