Hey guys, how would you do this question?
A shell is fired from the ground at 400km/h at the instant when it is vertically overhead. The initial speed of the shell is 100m/s.
(a) Find the angle of projection theeta of the shell, if it eventually hits its target.
(b) If the aeroplane flies at a constant height of 2km, find the time when it is hit by the shell.
There is another question and its diagram attached below.
