Rae dropped a bowling ball from a height of 8 meters. At which distance above the ground was the ball MOST likely moving at the greatest speed?
Still accelerating til it hits earth. ====================================== The height from which she dropped the ball is irrelevant. In any case, the ball was most likely moving at the greatest speed just as it hit the ground. The answer to the question is: zero.

As the speed of a bicycle moving along a horizontal surface increases from 2 meters per second to 4 meters per second the bicycle's gravitational potential energy?
There is no change. The bike is moving along a horizontal surface, and only a change in height can change the gravitational PE.
What is hitch height on a 22 foot Penske moving truck?
The top of the hitch ball should be aprox 19-20 inches from the ground.
If a stone falls past a bird on a ledge moving at 4 meters per second how fast will the stone be moving just before it hits the ground below 9 seconds later?
92.2m/s
Head injuries could happen while cycling?
Sure. Cyclists are moving at speed, with their heads at a height above ground. If they fall, they may bang their heads.
You are seated in a train that is stopped at a station Use two different reference points to explain that the train can appear to be moving and not moving?
the person standing on the ground, the train is moving and the ground is stationary. but the person on the train looks he is stationary and the ground is moving.
Looking at the ground besides a moving car helps you judge its?
Location (dirt road, asphalt), speed (appx.), height, and possibly if it has any issues (leaks, debris)
What are Reference points to explain that train is moving?
A person standing on the ground. For the person on the train, ground is moving and the train is stationary.
When a coconut falls when does it have gravitational potential energy?
An object has potential engergy when it is any height above the ground. The object does not have to be moving to have engergy. This is like a stored energy. It takes energy to move or raise an object to a height level. This object now has stored that energy.
Jack can run at 75 meters in 10 seconds how fast is he moving?
Jack is moving at a speed of 7.5 meters per second.
Give an example of an object that has no net force acting on it?
Kinetic Energy is the energy of motion, so anything that is moving has kinetic energy. Examples : a ball rolling down a ramp a spoon falling off a table a baseball hurtling towards a window a moving train a coin falling from the roof of a building (generally anything with a rest mass which isn't at rest)
