The 10-kg slender rod ac is suspended from the fixed pin at aand is 1.5 m long. a 1.5-kg ball strikes the tip of the rod with a horizontal velocity of 8 m/s and the impact has a coefficient of restitution of e= 0.75. determine the velocity of the ball immediately after impact, vb2, the velocity of the tip of the rod immediately after impact, vc2, the velocity of the center of gravity of the rod immediately after impact, vg2, and the angular velocity of the rod immediately after impact, ω2.
