Chapter 5, Problem 64GP

As it pulls itself up to a branch, a chimpanzee accelerates upward at 2.2 m/s² at the instant it exerts a 260-N force downward on the branch. The situation is shown in Figure 5-43.(a) In what direction is (i) the force the branch exerts on the chimpanzee; (ii) the force the tree exerts on the branch; and (iii) the force the chimpanzee exerts on the Earth? (b) Find the magnitude of the force the chimpanzee exerts on the Earth.
