a small cart of mass 4 kg slides down from the top of a curved track of unknown length. it first passes a patch of rough surface, and then it hits a spring of rest length 1.85 m and stops. the spring is also located on a second patch of rough surface. if height of the curved track is 4 m, the cart's velocity after passing the first rough patch is 2 m/s, and the coefficient of kinetic friction is 0.47,what is the length of the first rough patch in meters? use g
