Hey
I just need some help with intepreting this question. I've allready solved the first part (A), but I am not sure as to when the time t1 occurs. Heres the question:
(A) A particle is progected with speed u at an angle alpha to the horizontal. If the maximum height reached is the same as the total horizontal range, show that tan alpha = 4
(B) The particle moves at right angles to its original direction of motion after a time t1 and then strikes the horizontal plane after 8s, both times measured from the instant of projection.
Show u = g(root)17
Calculate t1
Ok, so I've shown tan alpha = 4 and u = g(root)17, but i don't know when t1 occurs. Is it when the maximum vertical height is achieved? Any help is appreciated.
Thanks in advance
