1. The problem statement, all variables and given/known data A bowling ball with radius (R) and mass (m)hit the ground and traveled a distance (d) before it started to roll due to the force of friction cause by the coefficient of friction (mu) between the ball and the lane. 2. Relevant equations I=2/5mR^2 F=ma torque=I*alpha F(friction)=mu*F v=w*alpha 3. The attempt at a solution Express the distance d in term of R, m, v and mu.
