Consider a mass m which is attached to the origin by a rope of length R, and is free to swing under the influence of gravity. In other words, it is constrained to be on the inside surface of a frictionless sphere of radius R. Find the equations of motion, denoting θ as the angle that the rope makes with the vertical (θ = 0 is straight down) and φ as the normal angle in the xy plane.

Spiderman, whose mass is 78.0 kg, is dangling on the free end of a 11.6-m-long rope, the other end of which is fixed to a tree limb above. By repeatedly bending at the waist, he is able to get the rope in motion, eventually getting it to swing enough that he can reach a ledge when the rope makes a θ = 61.2° angle with the vertical. How much work was done by the gravitational force on Spiderman in this...

Batman, whose mass is 80 kg, is holding onto the free end of a 12-m rope, the other end of which is fixed to a tree limb above. He is able to get the rope in motion as only Batman knows how, eventually getting it to swing enough that he can reach a ledge when the rope makes a 60° angle with the downward vertical. How much work was done against the force of gravity in this maneuver? Pleas explain...
