(b) the path can be a straight line or circular and the ball travels with uniform speed
(c) all parts of the ball have the same velocity and the velocity is constant
(d) the centre of the ball moves with constant velocity and the ball spins about its centre uniformly
Solution:
The correct option is (c) all parts of the ball have the same velocity and the velocity is constant
