A painter in a crate which hangs alongside a building, weighs 1000N.When the painter pull on the rope, the force he exerts on the floor of the crate is 450N. If the crate wieghs 250N, find the acceleration.

3 answers

There is an upward force of 500 N on the crate plus painter, due to both ends of the rope he is pulling. There is a downward gravity force of 450 N, resulting in a net force of 50N up.

a = Fnet/Mtotal = 50/(1250/g)= g/25
but the answer given is 2?
I don't understand how to find the resultant force, who can help me?
