# What is the amount of work done in moving the box from the bottom to t

## Homework Statement

A 160 Newton box sits on a 10 meter long frictionless plane inclined at an angle of 30° to the horizontal as shown. Force (F) applied to a rope attached to the box causes the box to move with a constant speed up the incline.

Calculate the amount of work done in moving the box from the bottom to the top of the inclined plane.

So far i come up with h=u*t-0.5*g*t^2, but now sure where to go

What is "h" and what is "u"?

There is a simple way to do this based on conservation of energy. None of the energy is lost to friction.

The problem says to find the work done.

Work is (or "causes") a change in energy.

Does the box change it's energy at all from the bottom of the incline to the top?
