A football kicked vertically upward from a height of 7 feet with an initial speed of 50 feet per second. The formula h=7 + 50t-16t^2 describes the balls height above the ground, h,in feet, t seconds after it was kicked.use this formula to find the balls height 2 seconds after it was kicked.
To find the ball's height 2 seconds after it was kicked, we substitute t = 2 into the formula for h:
h = 7 + 50t - 16t^2
h = 7 + 50(2) - 16(2)^2
h = 7 + 100 - 16(4)
h = 7 + 100 - 64
h = 107 - 64
h = 43
Therefore, the ball's height 2 seconds after it was kicked is 43 feet above the ground.
