Discuss the advantages of having a topspin on a ball by obtaining expressions for the friction force and energy loss. Conduct this analysis for the case of no sliding. What happens when the topspin is high enough so that the contact point C has zero horizontal velocity immediately before impact?

Q150;

A solid sphere of mass m and radius R makes contact with a surface while its center of mass velocity is vG = vxi − vzk and angular velocity is zero. Find the value of the smallest coefficient of friction that will cause the sliding to end during the compression stage.
