It's kinetic energy as the ball the ball isn't raised above the ground it does not have any gravitational potential energy.
To find the kinetic energy of the ball you will have to use the formula:
KE=0.5 x m x v squared
m being mass and v being velocity
so the calculation is:
0.5 x 2 x 10 x 10= 100J

*to became popular on stock markers
*to be known as a good business
Answer:
* Temperature changes
* Changes in the tension
* Errors in the meter marks
Explanation:
When we are using several meters to make a measurement we have several aspects that can cause the readings to differ.
* Temperature changes make the dilation between readings different, at higher temperatures the material of the meter expands and the reading decreases.
* Changes in the tension with which the meter is pulled to keep it straight, in general all materials bend under the action of gravity, so you have to pull them to make them straight, if the forces are different from the material is lengthened decide Young's modulus, inducing different readings
* Errors in the meter marks, especially in the initial part that is covered by a hook, different positions of the hook change the readings.
* Structural problems, such as rust, bends that create changes in the length of the meter material.
The correct answer is: <span>X, W, Y, Z
In fact, the elastic potential energy of a spring is given by
</span>
<span>where k is the spring constant and x is the stretching of the spring with respect to its rest position.
In this problem, all the four springs are stretched by the same distance x. This means that their difference in potential energy is due only to the difference between their spring constant: the larger the spring constant, the greater the energy. Therefore we can list the springs from the one with largest spring constant to the one with smallest constant, and this list corresponds to listing the springs from the one with largest energy to the one with smallest energy:
X, W, Y, Z</span>
