The football is punted with an initial velocity of 22 meters per second from a height of 1 meter off the ground. When is the football within 5 metes of the ground?

Is the ball punted straight up? If so, then
h = 1+22t-4.9t^2
So, just solve for t when h<=5.
If the ball was kicked at an angle, things get a bit harder, as the equation is then
h = 1 + 22sinθ t - 4.9t^2
h = 1+22t-4.9t^2
So, just solve for t when h<=5.
