Question

A gorilla is hanging motionless on a tree branch. If the gorilla's weight is 400 Newtons, what must be the tension in the tree branch?

Answer 1

let's convert 400 newtons to Kg, which is 40.7886.

now we put it in a formula that includes gravity and acceleration

(40.7886 kg) ( 9.8 m/s2) + (40.7886 kg) (0)

now we come up with the answer of 399.72828 kg or 3920 Newtons

Not sure which unit you are looking for but they are both there.
