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 = ?

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