A ball is kicked into the air and follows the path described by
h(t)= – 4.9t^2 + 6t + 0.6, where t is the time in seconds and h is the
height in meters above the ground. Find the maximum height of the
ball. What value would you have to change in the equation if the
maximum height of the ball is more than 2.4 meters?
