The system is released from rest with no slack in the cable and with the spring unstretched. Determine the distances traveled by the 4.5-kg cart before it comes to rest (a) if m approaches zero and (b) if m= 2.8 kg. Assume no mechanical interference and no friction. The distances is positive if up the incline, negative if down. k = 160 N/m 4.5 kg m Answers: (a) m = 0, (b) m = 2.8 kg. 28° S= i S= i m
