Step-by-step explanation:
<u>First Problem</u>
The ball hits the ground when , therefore:
and
Since the ball is in the air before it hits the ground, (seconds) is the more appropriate choice.
<u>Second Problem</u>
The maximum height of the ball is determined when , therefore:
This means that the height of the ball is at its maximum after 3.34 seconds:
Thus, the answer is 54.55 (meters).
<u>Third Problem</u>
Refer to the second problem
<u>Fourth Problem</u>

Therefore, the height of the ball after 4.3 seconds is 50.01 (meters).
<u>Fifth Problem</u>
The ball will be 24 meters off the ground when , therefore:
Therefore, the ball will be 24 meters off the ground after 0.84 (seconds) and 5.83 (seconds)
