An object projected upwards from the top is a tower reaches the ground in 9 seconds. The same object projected downward with the same speed reaches the ground in 4 seconds. How long would it take the object to hit the ground if it were simply dropped?
If the object were simply dropped, it would take the same amount of time to reach the ground as the object projected upward. Since the object projected upward takes 9 seconds to reach the ground, it would take the same amount of time for the object to hit the ground if it were simply dropped: 9 seconds.
