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?
1 answer
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.
