The elements of a device designed to measure the coefficient of restitution of batbaseball collisions are repeated

Question:

The elements of a device designed to measure the coefficient of restitution of bat–baseball collisions are repeated here from Prob. 3/265. The 1-lb “bat” A is a length of wood or aluminum which is projected to the right with a speed vA = 60 ft/sec and is confined to move horizontally in the smooth slot. Just before and after the moment of impact, body A is free to move horizontally. The baseball B weighs 5.125 oz and has an initial speed vB = 125 ft/sec. Determine the immediate post-impact speed vB′ of the baseball and the resulting horizontal distance R traveled by the baseball over the range 0.4 ≤ e ≤ 0.6, where e is the coefficient of restitution. The range is to be calculated assuming that the baseball is initially 3 ft above a horizontal ground.
