Do you have solution for this Question. If yes    I aslo want solution.

Q.


A A Bowler releases his ball at a speed of 3m/sec. If the ball has a diameter of 250 mm, what spin w should be put on the ball so there is no slipping? If he puts on only half of this spin w, keeping the same speed of 3 m/sec., what is the speed after .3 sec.? The ball has a mass of 1.8 kg and a dynamic coefficient of friction with the floor of .1. Neglect wind resistance and rolling resistance (as discussed in Section 7.1).
