A bowler uses a lane with a coefficient of kinetic friction of 0.165. The bowler releases her 5,96kg bowling ball with a translational speed of 3.40 m/s. At the moment of release, the ball is not rotating. As the ball slides, it begins to rotate. Use g = 9.81 m/s^2 for acceleration due to gravity. What is the Wnc done by friction on the ball before it transitions to rolling without slipping? Wnc = = ? J

Problem #4 (. A 16-lb bowling ball is cast horizontally onto a lane such that its initial angular rate wo = 0 and its center of mass has a velocity vo = 8 ft/s. The radius of the ball is r = 0.375 ft, and the coefficient of kinetic friction between the lane and ball is Hk = 0.12. 8 ft/s G What is the condition, in terms of w and v for а. 0.375 ft rolling without slipping? b. ) Draw a clear and complete free body diagram of just the ball. с. What is the angular acceleration of the ball? Use IG = l5 mr for a solid sphere. What is the linear acceleration of the ball? е. For how much time does the ball slide before it begins to roll without slip? f. For what distance does the ball slide before it begins to roll without slip? g. What is the velocity of the ball at the moment it beings to roll without slip? d.

A 4 kg ball moving to the right at 6 m/s and a 3 kg ball moving to the left at 8 m/s on a horizontal smooth plane along a straight line. Determine the speed of the 3 kg ball after impact if the impact is elastic.
