The 3-lb block A is hanging in the stationary position shown when it is hit by the 5-oz ball B. If the velocity of ball B just before it hits

block A is 40 ft/s as shown, determine the velocity of ball B and the velocity of block A immediately after the impact (Specify the direction of the results). Assuming the coefficient of restitution between A and B is e = 0,7. Determine the maximum angle 0that block A swings through.
