A 75.0 kg football player jumps up 0.79 m (reaches a maximum height of 0.79 m above the ground where he catches the pass) to catch a pass. To give himself the vertical speed necessary to make the jump, he bent his knees and dropped his center of mass 0.61 m. Then he pushed off over that distance of 0.61 m until he left the ground with the speed necessary to reach a height of 0.79 m after leaving the ground. How much force did the player exert against the ground to make this jump?
