One day at football practice, Darrell, the kicker, punted the ball so that its height in feet above the ground was given by the
Tju [1.3M]

The height of the all after 2 secs is 86 feet

<h3>Functions and vales</h3>

Given the height in feet above the ground was given by the following function h(t) = -16t^2 + 75t

where:

t is the number of seconds since the ball was punted.

If the value of t = 2s, hence;

h(t) = -16t^2 + 75t

h(2) = -16(2)^2 + 75(2)

h(2) = -64 + 150
h(2) = 86

Hence the height of the all after 2 secs is 86 feet
