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
−2
.

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

their crystal patterns have been disrupted by stress

it is a negative acceleration

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
