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?

1. A box is being pulled up a 40° incline by a 7.0 kg block suspended from a frictionless, massless pulley. The box does not start at the very bottom of the incline. The block is suspended 2.0 m above the ground. The coefficient of kinetic friction between the box and the incline is 0.40. The block is released from rest. At the moment the block hits the ground, the box is traveling at 2.0 m/s up the incline. What is the mass of the box?
