Question: (I need help with B, C, and D)

GPE NET TH TKE 15 H H ing on the man. [ 313. A] Explain how the principle of energy conservation applies to a man sliding from rest clown a vertical pole if there is a constant friction force acting on him. [ 3] The man slides down the pole and reaches the ground after falling a distance of 15 m. His potential energy at the top of the pole is 1000 J. Assuming friction still acts on the man as he moves: B) Sketch a graph to show how his gravitational potential energy varies with h. Label this graph GPE. [ 2 l C] 0n the same graph. sketch how his translational kinetic energy varies with h. Label this graph TKE. [ 2] D] Using your graphs. describe the signicance of your sketches in validating that constant forces are acting on the man. [ 3]
