A bowling ball of mass 7.1 kg and diameter 21.6 cm is thrown down the alley at a speed of 9.5 m/s. The bowling ball is initially skidding, not rolling, down the alley. The coefficient of friction between the ball and the alley is mu_k= .25 and mu_s= .30
Find the following information:
How far does the ball travel while skidding before it starts to roll?
What is the final angular velocity and linear velocity?
How long of a time does the ball skid for?
