11. A ball is thrown upward at a velocity of 15 meters per second from a height that is 20
meters above the ground. The height h (in meters) of the ball at time t in seconds) after it
is thrown can be found by h(t) = -5t^2 + 15t + 20. Find the time when the ball is again 20
meters above the ground.
