A model train with a mass of 1 kg is moving along a track at 24 (cm)/s. If the curvature of the track changes from a radius of 96 cm to 180 cm, by how much must the centripetal force applied by the tracks change?

(F1)/(F2)=(r2)/(r1)
F1=96/180F2

Explanation:

Centripetal force,
F=(mv^2)/r
F is inversely proportional to r , where r = radius of the track
