A projectile is fired with an initial speed of 113m/s at an angle of $60.0^{\large\circ}$ above the horizontal from the top of a cliff 49.0m high.Determine the tome to reach maximum height,maximum height above the base of the cliff reached by the projectile.

Question

$\begin{array}{1 1}t = 10s, \quad h=538 m\\t = 5s, \quad h=538 m\\t = 5s, \quad h=489m\\t = 10s, \quad h=489 m\end{array} $
