A38-kilogram child roller skates on a circular track with a radius of 24 m. her velocity is 6.0 m/s. what centripetal force does she experience?

-0.16 n
-0.38 n
-57 n
-580 n

In order to solve the problem presented above you will simply need to use the formula shown below. Please see attachment. Now all we have to do is simply replace the variables with the information that the problem gives us. If we do that we will get the following:

F = m*v²/r

F = 38*6²/r

F = 38*36/24

F = 57 Newtons

I hope it helps, Regards.
