A model train with a mass of 3 kg is moving along a track at 12 (cm)/s. If the curvature of the track changes from a radius of 4 cm to 18 cm, by how much must the centripetal force applied by the tracks change?

Explanation:
Let mass of train m =3kg = 3000 g
Velocity of train v = 12cm/s
Radius of first track
Radius of Second track
we know the centrifugal force =
Decrease in force in this case
