A model train, with a mass of 4 kg4kg, is moving on a circular track with a radius of 3 m3m. If the train's kinetic energy changes from 8 j8j to 48 j48j, by how much will the centripetal force applied by the tracks change by?

Explanation:
Given we have to find the centripetal force on a model train of mass
The centripetal force of a body is
Substituting
Here,
So, change in centripetal force applied by tracks change by
Um.....yeah, that's why you end up with
