Question

an inclined plane id 10 meters high. an effort force of 200 newtons id required to pull an 800 newton cart up the incline.

what is its innput.

it output.


its work done against friction.

Answer 1

Input and output could refer to work or to force. Since you don't have enough information to calculate the input work(You'd have to know the coefficient of kinetic friction.), I'll assume it refers to force here. The input is the force applied to the system, which is given as the effort force of 200 N. The output is the resistance force that is overcome, which is the 800 N weight of the cart.
