A 1 kg ball initially travelling at 7 m/s strikes on the lower end of a 5 kg bar AB, as shown in Figure Q2(a). The bar is hinged at A and is initially at rest. The
coefficient of restitution between the rod and sphere is 0.7.

Determine the angular velocity of the bar and the velocity of the ball
immediately after impact.
