A small cart of mass 5 kg slides down from the top of a curved track of unknown length. It first passes a small patch of rough surface, and then it hits a spring of rest length 1.63 m and stops. The spring is also located on a second patch of rough surface. If height of the curved track is 1 m, what is the velocity of the cart in m/s after passing the rough patch with coefficient of kinetic friction 0.2 and distance 2.15 m? m h k d
