VB = 12 m/s, The coefficient of restitution e is given in the table. Determine the magnitude and direction of the velocity of each ball after the impact. Problem 3. The 4-kg spool slides along the rotating rod. At the instant shown, the angular velocity and angular acceleration of the rod is = 6 rad/s and 0-2 rad/s². At this same instant, the spool is moving outward along the rod at 3 m/s and acceleration Im/s², where r is given in the table. Determine the radial friction force and the normal force of the rod on the spool at this instant. VA VB Fig.1 VA Fig.2 VB Fig. 3 -3 m/s
