A football is kicked vertically upward from a height of 6 feet with an initial speed of 55 feet per second. The formula h = 6 + 55t-16t² 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 3 seconds after it was kicked. The ball's height, 3 seconds after it was kicked, was feet.
