A factory worker pushes a 30.5 kg crate a distance of 4.60 m along a level floor by pushing downward at an angle of 28.0 below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.260. The Crate is Pushed with a Constant Velocity For the first set of questions, assume that the crate is being pushed with a constant velocity. Part A) Part complete How much work is done on the crate by the worker's pushing force when the crate is pushed a distance of 4.60 m ? Part C) How much work is done on the crate by the force of friction during this displacement
