Afootball player pushes a sled on a level surface with a weight force of 760 n that acts perpendicular to the surface. the coefficient of kinetic friction between the sled and grass is 0.78 how much work does the football player perform if he pushes the sled and displaces it 10 m. assume ) the average force performed is equal to the force required to keep the sled in motion and 2) the applied force is paraîlel to the sleds displacement. (3 points) a. b. how much power did the football player produce if he performed the sled push in 3.21 seconds? (2 point)
