Suppose that the coefficient of kinetic friction between Zak's feet and the floor, while wearing socks, is 0.250. Knowing this, Zak decides to get a running start and then slide across the floor.   If Zak's speed is 3.00 m/sm/s when he starts to slide, what distance ddd will he slide before stopping? Use 9.81 m/s2m/s2 for the acceleration due to gravity.
