A soccer player, with a mass of 75.0 kg, slides on the ground to celebrate a goal. At the start of the slide, the player moves at a speed of 3.30 m/s before coming to rest. The coefficient of friction between the player and the ground is 0.700. (a) Find the change in mechanical energy of the player (in J) from the start of the slide to when she comes to rest. How is kinetic energy related to mass and speed? Note that the change in kinetic energy is the final value (at rest) minus the initial value at the start of the slide. J (b) How far (in m) does the player slide?
