1. The problem statement, all variables and given/known data A worker pushed the Piano weighing 93N up a ramp into a moving van, pushing horizontally, parallel to the ground. The ramp extends 4m over the ground and 3m high. The top, sloped surface of the ramp holding the piano is 5m long. The worker exerts a force of 85 N. How much work does she do? 2. Relevant equations W = Fd 3. The attempt at a solution I suppose I could use arctan or something to find the angle and use cosine, but would the angle for the physical situation be the same as the angle for the force vector?
