A ball is struck at ground level and projected with a speed of 16 m/s-at a FIXED angle θ to the horizontal.
The parametric equations of the path of the ball are given by
? = 16?????,
? = 16????? − 5?2
(i) By eliminating t show that the Cartesian equation of the path can be written as a quadratic in tan θ.
I can eliminate the 16t's but I cant for the life of me get rid of the 5t2
I tried
x/y = tan? - (5t2)/16tcos? but where from there I have no clue. Any help hugely appreciated
