Well, isn't that just a happy little question! When a quarter is dropped from a tower, its velocity after 10 seconds can be calculated using the formula: velocity = acceleration due to gravity x time. Since the acceleration due to gravity is approximately 9.8 m/s^2, the velocity of the quarter after 10 seconds would be 98 m/s. Just imagine that quarter gracefully falling through the air, creating a beautiful moment in time.
Since velocity increases about 10 m/s every second (due to gravity), it'd be about 100 m/s. However, that number's fairly approximate and ignores air resistance.
The acceleration of the stone when it is dropped from the top of a tower is equal to the acceleration due to gravity, which is approximately 9.8 m/s^2 downward. This acceleration remains constant as the stone falls towards the ground, neglecting air resistance.
v = a X t. a = 9.8 m/s2 (acceleration) and t = time. At t = 2 seconds, v = (9.8 m/s2) X (2 s) = 19.8 m/s. At t = 4 seconds, v = (9.8 m/s2) X (4 s) = 39.6 m/s. [ANSWER: at t = 2 s, v = 19.8 m/s ; at t = 4 s, v = 39.6 m/s. ]
If we can use the approximation that we're at or near the surface of the earth and gravity = 9.8 m/s2, then we don't really care where the man is standing when he initiates this experiment ... it doesn't matter.All we're really trying to determine is how long it takes a ball tossed upward at 20m/s to return to its original altitude.And that's just double the time it takes a dropped object to reach a downward velocity of 20 m/s.V = 2 a tt = V/a = 20/g = 20/9.8 = 2.041 secondst = 2 x the gravity-drop = 4.082 seconds (rounded)
As the ball falls from the tower, it accelerates due to gravity. Its downward velocity increases as it falls, while its potential energy decreases. The ball's acceleration is approximately 9.81 m/s^2 (assuming no air resistance).

19.6 meters / 64.4 ft
distance = speed x time so the distance is just the speed of the stone x 8 seconds
it is a tower yeah
Galilieo. He dropped it from the leaning tower of Pisa. In ITALY,
The duration of Tower Prep is 2700.0 seconds.
The duration of Mäch Tower is 90.0 seconds.
He dropped an apple from a tower.
Galileo did.
The duration of Tower of Terror II is 27.0 seconds.
