Question

The circumference of an orbit for a toy on a string is 18 m and

the centripetal force is 12 N. Does the centripetal force do any work on the toy when it follows its orbit for one cycle?

Answer 1

it does

Step-by-step explanation:

To determine if the centripetal force does any work on the toy when it follows its orbit for one cycle, you need to know the displacement of the toy during that time. The displacement is the distance the toy moves in a particular direction, and it is equal to the circumference of the orbit in this case. If the displacement is non-zero, then the centripetal force does work on the toy. In this case, since the displacement of the toy is 18 meters, the centripetal force does work on the toy when it follows its orbit for one cycle.
