2016 F = ma Exam — Question 17

As shown in the figure, a ping-pong ball with mass m with initial horizontal velocity v and angular velocity ω comes into contact with the ground. Friction is not negligible, so both the velocity and angular velocity of the ping-pong ball changes. What is the critical velocity v such that the c ping-pong will stop and remain stopped? Treat the ping-pong ball as a hollow sphere. v ω
