3. A bowling ball of mass m and radius r is launched with speed vo (having nospin) on a lane at an alley with a coefficient of friction of μ. How far willit travel before it starts to roll without slipping? What will its speed bewhen this happens? Hint: The frictional force exerts a force that causesthe speed to decrease linearly at a constant rate. The friction forcecauses a torque about the center of the bowling ball that in turn causesthe angular velocity to increase linearly at a constant rate. There will bea time at which the bowling ball stops slipping and starts rolling.

Note: The angular momentum will remain conserved. Since there is no external net torque acting on…
