The pilot of an airplane traveling 180km/h wants to drop supplies to flood victims isolated on a patch of land 160m below. The supplies should be dropped how many seconds before the plane is directly overhead?

  • science -

    h = Vo*t + 0.5g*t^2 = 160 m.
    0 + 4.9t^2 = 160
    t^2 = 32.65
    t = 5.7 s. = Time to strike ground.
