Question 2

A ball $S\,$ is thrown from a point $O\,$ with initial speed $\text{ ms}^{-1}$ at an angle of elevation $θ\theta$ . After traveling a horizontal distance $x$ , its height above the level of $O\,$ is $y$ .

a.

Show that

\tan \theta - \frac{g x^2}{2 V^2 \cos^2 \theta}

[4]

b.

Given that $θ=45∘\theta = 45^\circ$ and that when $x = 10$ , $y = 2$ , find the speed of $S\,$ at the point where $x = 10$ and $y = 2$ .
