Which two factors are used to calculate kinetic energy? A. The velocity of an object
B. The mass of an object
c. The height of an object
D. The chernical formula for the object
I E. The density of an object

The velocity and mass of the object

To solve this problem it is necessary to apply the kinematic equations of movement description, where the speed of a body is defined as the distance traveled in a given time, that is to say

where,

x = Displacement

t = time

Since the moon is making a path equal to that of a circle, we know by geometry that the perimeter of a circle is given by

At the same time we have that time is equal to

Using the equation for velocity we have finally that

Therefore the speed of the Moon in its orbit is 987.92m/s
