An object is dragged 6 m up a ramp under a constant force of 27 N applied at an angle of 32° to the ramp. How do i calculate the work done?

Answer 1

Work done by F = integral of F•ds

= F • s for a constant force = Fscosθ = (27N)(6m)cos(38°)

The ramp is irrelevant as you are given the force you exert and the direction with respect to the ramp. Also you are not calculating net work including the effects of gravitational force or friction.
