Question

a football is kicked vertically upward from a height of 3 feet with an initial speed of 60 feet per second. the formula ( h = 3 + 60t - 16t^2 ) describes the ball’s height above the ground, ( h ), in feet, ( t ) seconds after it was kicked. use this formula to find the ball’s height 1 second after it was kicked.
the ball’s height, 1 second after it was kicked, was (square) feet.

Explanation:

Step1: Substitute t=1 into formula

Substitute $t=1$ into $h=3+60t-16t^2$:
$h=3+60(1)-16(1)^2$

Step2: Calculate each term

Compute each part:
$h=3+60-16$

Step3: Sum the values

Add and subtract the terms:
$h=63-16$
