a pilot tries to drop a bag of flour from an airplane flying horizontally at 55.56m/s onto a target on the ground 250m below. with what velocity must he throw the flour up or down if he is foced to release it when he is 500m horizontally from the target.

Horizontal:
t = D/r = 500/55.56 = 8.99928s
Vertical:
s = s(zero) + v(zero)t + (1/2)at^2
250 + v(zero)(8.99928) - 4.9(8.99928)^2 = 0
8.99928v(zero) = 16.3164m/s [up is positive]

calculate the time it takes the bag to hit the ground form the airplane then make that the time in the ds/dt equation to see total velocity you would need to hit the target then subtract the velocity of the airplane
