h = Vy*t + 0.5g*t^2 = 840 m.
0*t + 4.9t^2 = 840
Solve for t.
A cargo plane is moving with a horizontal velocity of
vx = +230 m/s
at a height of
y = 840 m
above level ground as shown in the figure below when it releases a package. Ignoring air resistance, how much time will it take the package to reach the ground? (Express your answer to the nearest tenth of a second.)
