Q4: The system is released from rest with no slack in the cable and with the spring unstretched. Determine the distanced s traveled by the 10-kg cart before it comes to rest (a) if m approaches zero and (b) if m = 2 kg Assume no mechanical interference [Ans.: (a) s = 0.663 m, (b) s = 0.349 m ] 10 kg 25 772 k = 125 N/m
