baloonist drops rock from balloon. takes 7 seconds for the rock to fall. what's the balloonist's altitude in feet?

  • 7th physics - ,

    It will depend upon whether the balloon is rising or falling when the rock is released.

    If the balloon altitude is constant at release of the rock,

    Y = (g/2)*t^2
    is the distance it falls in time t

    g = 32.2 ft/s^2 t = 7 s

    Solve for the altitude Y
