A soccer player, with a mass of 71.0 kg, slides on the ground to celebrate a goal. At the start of the slide, the player moves at a speed of 3.90 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. (b) How far (in m) does the player slide?
