The acceleration of gravity is 9.8 meters (32.2 feet) per second2.
After 3 seconds, the speed of the falling rock is 29.4 meters (96.6 feet) per second.
The rock's average speed during the 3 seconds is 14.7 meters (48.3 feet) per second.
The distance it has fallen = (average speed) x (time) = 44.1 meters (144.9 feet).

Lifting an object to a greater height requires more energy, but not any more force, thanlifting it to a not-as-great height.
Which combiation of features will have the greatest gravitational potential energy?
A large mass raised to a great height will.
Which of these would have the greatest potential energy?
the object that has the most potential energy is whatever is not moving but is ready to move like flinging a rubber band let's say you holding it back now it has energy stored in it then once you let go and it flings it has kinetic energy which is a different story but that is my answer F.Y.I kinetic energy is when it energy is being used and dies down back into potential .......... get it now ;);0

If you drop a rock from a great height about how fast will it be falling after 5 seconds neglecting air resistance?
The object will be falling at 49 m/s.This is solved by multiplying the force of gravity (9.8 m/s) by the time you're calculating (5s).
