Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

A 4. You hit a tennis ball with an initial vertical velocity of vo, of 25 m/s. The ball leaves the tennis racket 2 meters above the ground, ho. How much time does your opponent have before the ball hits the ground on the other side of the net, h(t)?
Use h(t) = -5t² + vot + ho
where h(t) is the height of a tennis ball being hit
ho is the initial height
vo is the velocity in meters/second after time (t) in seconds
O t= 0.08 seconds
O t= 0.23 seconds
O t= 5.08 seconds
t = 25.02 seconds
