The height of a baseball after being hit by a batter is given by h(t) = -16t2 + 60t + 4 (where h(t) is the
height and t is the time after hitting the ball). You are asked to find the time it takes the ball to hit the
ground. After substituting zero for the height and solving using the quadratic formula, you determine
that the time is approximately -0.07 and 3.82 seconds.
