Physics Question – Newton’s Laws?

As a chimpanzee climbs up to a branch, it accelerates upward at a rate of 2.3 m/s² while exerting a downward force of 280 N on the branch. What is the magnitude of the force that the chimpanzee exerts on the Earth? Please express your answer with three significant figures and include the appropriate units.

net force = weight + applied force

m 2.3m/s² = m -9.8m/s² + 280N

solves to

m = 23 kg

and so his weight (the force he exerts on the Earth) is

W = 23kg * 9.8m/s² = 227 N
