A monkey is chained to a stake in the ground. The stake is 3.00 m from a vertical pole, and the chain is 4.11 m long. How high can the monkey climb up the pole? d
A child's swing is held up by two massless ropes tied to a tree branch. The distance between the ropes at the top of the swing is less than the distance between the ropes at the bottom, so that the ropes hang 14.01° from the vertical (see the picture). If the tension in each rope is 2.4 N, what is the weight of the swing?
