Projectile Help Please!
A helicopter resting on ground starts to accelerate uniformly upwards. After 30s a flare was fired horizontally from the helicopter. 10s later, the flare reached the ground. (g = 9.81m/s^2).
Calculate:
a)Acceleration of helicopter
b)Height from which flare was fired
c)Height of helicopter the instant flare reaches ground (assuming it continued its constant acceleration after flare was fired)
*****I have already been told that i must show my work before getting help but that is why i am here :(. I do not want the answer, i just want someone to point me in the right direction.
Thank you
