A sled having a mass M = 120 kg is sliding down a ramp, while pulling a hanging box with mass m = 30 kg upward. The sled is on a frictionless surface, the rope is light, and the pulley is light/frictionless. m 20 a) Draw free-body diagrams for both the sled and the hanging box. b) Calculate the acceleration of the sled and the tension in the rope joining the two masses. c) What mass should the hanging box have in order for the sled to slide down the ramp at a constant speed?
