A person (75.0 kg) holds a rope attached to a mass (58.3 kg) via a smooth pulley, as shown, on a slope of angle 0 = 44º. The person just manages to stand still smooth puley m a) Show that the tension force in the rope is 571.3 N. [1] b) What is the force of friction acting on the person from the ground? [2] c) The person then begins to walk down the slope, keeping hold of the rope. If they walk with a constant velocity of 20 cm/s for 2 minutes, what is the work done against gravity on the block? [2]
