Answer:

72.25 ft

Explanation:

The function that models the height of the ball is

$h(t) = 68t - 16 {t}^(2)$

The maximum height occurs at:

t = - (b)/(2a)

t = - (68)/(2 * - 16) = (68)/(32) = 2.125

We substitute t=2.125 to get:

h(2.125) = 68(2.125) - 16(2.125) ^(2)

h(2.125) = 72.25

The maximum height is 72.25 feet
