You need the amount of time that it took to fall the 45m.
When an object is dropped from a certain height, the time it takes to reach the ground is independent of the height (assuming no air resistance). Therefore, whether you drop the object from three times the initial height or the original height, it will still take the same time (T) to reach the ground.
Both the feather and the hammer will hit the ground at the same time when dropped from the same height in a vacuum. This is due to the principle of gravity, which accelerates all objects at the same rate regardless of their mass.
The height from which an object is dropped does not affect its average velocity. Average velocity depends on the overall displacement and time taken to achieve that displacement, regardless of the initial height of the object.
The acceleration of an object dropped from a height of 10 meters is approximately 9.81 m/s2.
When an object is dropped, it falls towards the ground due to the force of gravity acting on it. The object accelerates as it falls until it reaches the ground or another surface, where it comes to a stop.

as done in Galileo's experiment when he dropped a large rock and a feather from a tall tower both hit the ground at the same moment when dropped from the same height.
Both the feather and the hammer will hit the ground at the same time when dropped from the same height in a vacuum. This is due to the principle of gravity, which accelerates all objects at the same rate regardless of their mass.
If both objects have similar air resistance factors, they will both hit the ground together.
Assuming the object is dropped from rest and neglecting air resistance, it would take approximately 7.0 seconds for the object to hit the ground from a height of 500 feet. This is based on the formula t = sqrt(2h/g), where t is the time, h is the height, and g is the acceleration due to gravity (approximately 32.2 ft/s^2).
The height from which an object is dropped does not affect its average velocity. Average velocity depends on the overall displacement and time taken to achieve that displacement, regardless of the initial height of the object.
the height from which it was dropped
Because they undergo an acceleration. Free fall velocity is the function of a square.
The acceleration of an object dropped from a height of 10 meters is approximately 9.81 m/s2.
When an object is dropped, its potential energy decreases. This is because potential energy is a result of an object's position or height above the ground. As the object falls, it loses height, which leads to a decrease in potential energy. At the same time, the object gains kinetic energy, which is the energy of motion.

Interesting question. But when the object is at rest the potential energy of the object is 0, on the surface that is. When it is on a height h it's potential energy increase and when it is dropped from that height all that potential energy gets converted to kinetic energy just before hitting the ground. This extra force comes from this kinetic energy.
