Question

Write the equation you would use to calculate the velocity of the ball by using the concepts of conservation of energy. It is recommended that you use gravitational potential energy and kinetic energy to derive your equation for velocity.

Answer 1

$\begin{gathered} K\text{inectic energy = gravitational potential energy} \\ \frac{mv^2}{2}=mgh \\ \text{Solving v} \\ \frac{v^2}{2}=gh \\ v^2=2gh \\ v=\sqrt{2gh} \\ The\text{ equation for velocity is }v=\sqrt[]{2gh} \end{gathered}$
