Which of these is exhibiting kinetic energy?
a. a space station orbiting earth the high-energy phosphate bonds of a molecule of atp
b. a rock on a mountain ledge an archer with a flexed bow
c. a person sitting on a couch while watching tv

A.a space station orbiting Earth

Explanation:

As we know that kinetic energy given as

K.E.=1/2 m v²

Where m= mass

v= velocity

If the velocity of the object is zero then it posses zero kinetic energy.

We also know that when object at a height from the ground or from a reference line then it posses potential energy and it does not have kinetic energy because object is in rest position.

In the option B and C system is in rest position that is why these type of system posses zero kinetic energy.

So the answer is A.

A.a space station orbiting Earth
