A 700 lb floating platform is at rest when a 200 lb crate is thrown onto it with a horizontal speed of v0 = 12 ft/s. Once the crate stops sliding relative to the platform, the platform and crate move together with a speed of v = 2.667 ft/s. Neglect the vertical motion of the system and the resistance due to the relative motion of the platform with respect to the water. Determine the distance that the crate slides relative to the platform if the coefficient of kinetic friction between the platform and the crate is 0.25.
