You are trying to drop essential survival supplies from an aeroplane to help the survivors of a crash who are stranded. You are flying 300, m,300m above them, and your aircraft can travel no slower than 30, m, s, to the power minus 1 ,30ms −1
. You fly on a straight line which will pass over the survivors.

How far (in metres) in advance of overflying the survivors do you need to drop the package? Assume that the downward acceleration is 9, point, 8, m, s, to the power minus 2 ,9.8ms
