A 75 kg climber finds himself dangling over the edge of an ice cliff, as shown in the figure below. Fortunately, he's roped to a 940 kg rock located 51 m from the edge of the cliff. Assume that the coefficient of kinetic friction between rock and ice is 5.4×10−2. What is his acceleration, and how much time does he have before the rock goes over the edge? Neglect the rope's mass.

Part A: What is his acceleration?

Part B:

How much time does he have before the rock goes over the edge?
