Asked by Amanda and Leah

Pete slides a crate up a ramp at an angle of 20 degrees by exerting a 244 N force parallel to the ramp. The crate moves at a constant speed. The coefficient of friction is 0.19. How much work did Pete do when the crate was raised a vertical distance of 2.39 m? Answer in units of J
Answered by drwls
Force * distance = 244*(2.39/sin20)
= 1705 J

You do not need to know the coefficient of friction.
