A helicopter at rest on the ground started to accelerate uniformely upwards. After 30s a flare was fired horizontly from the helicopter. An observer on the ground measured the time the flare reached the ground as 10 seconds. Neglect air resistance.
A) acceleration of helicopter
B) height from which the flare was fired
c) height of the helicopter at the instant the flare reaches the ground, assuming acceleration remained constant
3.2 as acceleration is wrong
490m as distance is wrong.
I have absolutely no idea what other ways there are to solve it..
Also to know, the flare will make a parabola because of the velocity the flare takes from the helicopter
