Asked by jamie
A person pushes a block up a frictionless incline at a constant velocity. The incline is 35o, and the mass of the block is 28 kg. If he only exerts a horizontal force, how much work does he do if the block travels 7 m along the incline?

If he moves the block at constant velocity, and the incline is frictionless, the work he performs equals the potential energy increase achieved.
W = M*g*L*sin 35
W = M*g*L*sin 35
