An object is thrown vertically from a height of #6 m# at # 8 m/s#. How long will it take for the object to hit the ground?
Find the time it takes to reach the top of the projectile:
Knowing that at the top of the projectile the velocity is
Using that time, we can also calculate the distance to the very top:
So know we can know that the ball is a total of
To find the total time of the ball in the air, just add the times:
