\textbf{159-} A ball is thrown vertically upward from a height of 20 m above the ground with initial speed $V_0$. It reaches a height of 65 m above the ground. The speed of the ball becomes zero at ground level. If $g = 10\,\dfrac{\text{m}}{\text{s}^2}$, how many meters per second is $V_0$?
(Air resistance is negligible)
