Meriam, Kraige & Bolton — Kinetics of Particles: Problem 3_290

*3/290 The elements of a device designed to measure the coefficient of restitution of bat–baseball collisions are repeated here from Prob. 3/215. The 1-lb “bat” A is a length of wood or aluminum which is projected to the right with a speed \(v_A = 60 \text{ ft/sec}\) 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 \(v_B = 125 \text{ ft/sec}\). Determine the immediate post-impact speed \(v_B'\) of the baseball and the resulting horizontal distance \(R\) traveled by the baseball over the range \(0.4 \le e \le 0.6\), 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.
