A 165 lb student lands from a vertical jump and immediately jumps vertically again. The average ground reaction force is 1735 N which is applied for 0.33s. He was moving 1.2 m/s downwards when he first contacted the ground. What will his velocity be at takeoff? What will be his jump height?

    This problem is taken from Ahlborn's Zoological Physics, P 5.2. Two young people jump down from a height of h = 2.0 m onto the forest floor which has a mud hole and a rocky flat. The boy (M = 70 kg) lands with stiff legs on the muddy ground, which "gives" so that he depresses the ground by Delta_y = 5 cm when being decelerated from the impact velocity U_0 to 0. Determine the impact speed U_0. Calculate the...
