Meriam, Kraige & Bolton — Kinetics of Particles: Problem 3_104

3/104 The system is released from rest with no slack in the cable and with the spring stretched 200 mm. Determine the distance $s$ traveled by the 4-kg cart before it comes to rest (a) if $m$ approaches zero and (b) if $m = 3 \text{ kg}$. Assume no mechanical interference and no friction, and state whether the distance traveled is up or down the incline.
