Hi, I am new to this forum so please forgive my ignorance and very low standards of maths. I have been given a problem to solve that is just one part of a larger puzzle. Only this small part of the puzzle is mathematical.
The information I have been given is below.
"A rocket is launched. The launch was just off vertical, at an angle of 89.8968°. The rocket reached 174.6km above sea level before crashing back to ground not too far away. I need to know the distance the rocket travelled please. The distance horizontally from point of launch to point of landing.
* The rocket wasn't guided, nor propelled after take off. It followed the parabolic trajectory of a simple projectile.
* Both the launch point and landing site can be taken to be at sea level.
* Acceleration due to gravity is 9.81 m/s2.
* The effects of air resistance, the earth's rotation, etc., etc., etc. can be ignored."
Thanks in advance to anyone that can help. I would like to say that I have tried and failed with this one but I struggle to even start. I think I would need to know the velocity of the rocket but once again, not a clue where to begin.
