An outdoor chair is suspended from a tree by a single cable of length 1.5 m. The mass of the chair and the person sitting in it is a total of 85 kg. If someone pulls the chair through a horizontal distance of 80 cm and holds it there: a. What is the increase in the force exerted by the cable? b. How much sideways force must be exerted to hold the chair at that location?

A monkey of mass m = 10.0 kg is holding on to two vines each of length l = 3.00 m. The vines form an angle with the horizontal of 40.0 degrees (see figure). The monkey is not moving and the vines are considered massless and not stretchable. Determine the magnitude of the tension in each vine. d. Now the monkey moves up by clinging up the two vines, causing their angle with the horizontal to become smaller. If each vine breaks at a tension larger than T = 100 N, what is the smallest angel the vines can have with the horizontal?
