Mary pitches a ball. the initial height is 8 ft and velocity 80 ft per second. when will the ball hit the ground?

Initial velocity of the ball (u) = 80 ft/ sec

Final velocity of the ball after reaching the ground (v) = 0

Distance covered by the ball to reach the ground (s) = 8 ft

Let "a" be the acceleration of the ball.

We know,

Let "t" be the time required to reach the ground.

We know,

The ball will hit the ground in 0.2 second.
