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 

(b) If m = 3 kg. Assume no mechanical interference and no friction, and state whether the distance traveled is up or down the incline.

 

k = 150 N/m 4 kg 25 m
