Question: A 30-kg box is pulled upward 6.0 m from the rest by one constant force 90-N, along the surface of a frictionless ramp that rises

A 30-kg box is pulled upward 6.0 m from the rest by one constant force 90-N, along the surface of a frictionless ramp that rises at 370 above the horizontal. (a) How much work does gravity do on the box during this process? (5pts) (b) How much work does this constant force during this process? (3pts) (c) How much work does the normal force do during this process? (3pts) (d) What is the final speed of the box? (5pts)
