Question: A baseball player slides into third base with an initial speed of 8.35 m/s. If the coefficient of kinetic friction between the player and the ground is 0.36, how far does the player slide before coming to rest? How would I start this problem?? I would use Ff=uFn but it doesn't even give the weight of the player.. And would I have to use one of the kinematics problems to find the distance? If so, how would I find acceleration or final velocity?
