Caleb kicked a ball. The function h(t) = −8t2+40t describes the height of the ball, in feet, t seconds after he kicked it. How many seconds did the ball take to first reach 48 feet?
A ball is thrown in the air. The relationship between the time the ball is in the air in seconds (t) and the height of the ball in feet above the ground (h) is represented by h = −4t2 + 10t + 6. How many seconds will it take for the ball to hit the ground?
T = 2 seconds
