For the problem, use the discriminant to determine the number of real solutions for the equation. Then, find the solutions and check to see if they make sense in the context of the problem. A soccer player kicks the ball to a height of 2 meters inside the goal. The equation for the height h of the ball at time t is h = −4.9t2 − 3t + 4. Find the time the ball reached the goal. Enter the time to two decimal places. The equation has real solution(s). The soccer ball reached the goal after t ≈ seconds.
