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 maneuver? (kJ)

Spiderman, whose mass is 72.0 kg, is dangling on the free end of a 11.4-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 ? = 60.8
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...
Tarzan (whose mass is 90.0 kg) plans to swing down, starting at rest, from a ledge using a light vine 7.4 m long. He holds one end of the vine, and the other end is tied higher up on the tree, with the vine being 10 degrees from vertical. At the lowest point of his swing, he plans to let go and drop a short distance to the ground. If Tarzan missed the first chance to let go and drop...
