It is found that the time it takes for the projectile to hit the ground would be after 20 seconds.
<h3>When does the projectile hit the ground?</h3>
The projectile would hit the ground when its height h(t), is equal to zero.
The given function that models its height is given by:
where h is the height in meters and t is the elapsed time in seconds.
Then,
h(t) = 0
t = 20
Thus, The projectile hits the ground after 20 seconds.
