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?

Answer:

#(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
