A weather balloon is floating at a constant height above Earth when it releases a pack of instruments. If the pack hits the ground with a velocity of -68.5 m/s, how far does the pack fall?

a = -9.80 m/s^2
Vf = -68.5 m/s
d = ?

  • Physics -

    vf^2=vi^2+2ad where a= 9.8
    solve for d

  • Physics -

    d = Vf^2/2a
    d = -68.5/(2 x -9.80)
    d = 3.495 and this answer is being marked incorrect. Am i doing something wrong.
