Question

a football is kicked vertically upward from a height of 3 feet with an initial speed of 50 feet per second. the formula h = 3 + 50t - 16t² describes the balls height above the ground, h, in feet, t seconds after it was kicked. use this formula to find the balls height 1 second after it was kicked. the balls height, 1 second after it was kicked, was feet.

Explanation:

Step1: Substitute t = 1 into formula

$h = 3+50\times1 - 16\times1^{2}$

Step2: Calculate multiplication

$h = 3 + 50-16$

Step3: Calculate addition and subtraction

$h=37$

Answer:

37
