Question #95c33

Answer 1

This is a centripetal Force question

Explanation:

Centripetal force is:

`F_c = (mv^2)/(r)`

When you half the radius while keeping speed constant, the Force doubles.

This is an inverse proportion relationship.

In the case, if you were asked what would happen if you doubled speed, keeping all else constant, what would happen to the force?

Answer: The force would quadruple. Notice the square on the velocity variable.
