A model train, with a mass of #8 kg#, is moving on a circular track with a radius of #6 m#. If the train's rate of revolution changes from #5/3 Hz# to #1/4 Hz#, by how much will the centripetal force applied by the tracks change by?
The change in centripetal force is
The centripetal force is
The mass of the train,
The radius of the track,
The frequencies are
The angular velocity is
The variation in centripetal force is
