A rock is thrown vertically with a velocity of 21 m/s from the edge of a bridge 41 m above the river. How long does the rock stay in the air? V = 21 m/s d = 41 m a = -9.80 m/s^2 t = ?

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.

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 = ?
