A model train with a mass of #7 kg# is moving along a track at #12 (cm)/s#. If the curvature of the track changes from a radius of #32 cm# to #24 cm#, by how much must the centripetal force applied by the tracks change?
The change in centripetal force is
The centripetal force is
The mass is of the train
The velocity is
The radii are
The variation in the centripetal force is
The centripetal forces are
