Question 2A bowling ball (fig. 2) is cast on the alley with a backspin of = 10 rad/s while its centre O has a forward velocity of 0 = 8 m/s. Determine the velocity of the contact point A with the alley.

Question 3Block D shown in Fig. 3 moves with a speed of 3 m/s. Determine the angular velocities of links BD and AB, at the instant shown.
