Question

A baseball player swings and hits a pop fly straight up in the air to the catcher. The height of the baseball in meters t seconds after it is hit is given by the quadratic function . How long does it take for the baseball to reach its maximum​ height? What is the​ baseball?s maximum​ height?

Answer 1

Explanation:

Let the initial velocity of the ball is u.

At the maximum height the speed is zero.

Let the time is t.

Use first equation of motion.

v = u - gt

0 = u - g t

t = u/g

Let the maximum height is H.

Use third equation of motion

`v^2 = u^2 - 2 gh\\\\0 = u^2 - 2 gH\\\\H = (u^2)/(2 g)`
