Suppose that a rack Is thrown upward Nearly vertically from the edge of a 192 Foot tall cliff on mars IN Such a way that It will eventually hit the ground at the base of the clift . If the quitial velocity of the rack is by Ft/ sec, then the light of the stone IN feet, after & seconds is given by S = h () ) = - 6+ + 725+ 192 UND A FINd the velocity function, v (s ) of the rack D) How long will it take the rock to reach it's high point ? FFZI C) How long will the rock be at that time ? D) How long will it take until the rack M huts the ground at the base of the clift! ") with what velocity will the rack hit the
