Centripetal force = (4 \pi^2 m f^2 r)

(4 \pi^2 \times 12 , \text{kg} \times (1 , \text{Hz})^2 \times 6 , \text{m})

Centripetal force = (753.98 , \text{N})

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- A model train, with a mass of #2 kg#, is moving on a circular track with a radius of #5 m#. If the train's rate of revolution changes from #1/9 Hz# to #1/5 Hz#, by how much will the centripetal force applied by the tracks change by?
- A model train, with a mass of #3 kg#, is moving on a circular track with a radius of #8 m#. If the train's rate of revolution changes from #1/4 Hz# to #1/7 Hz#, by how much will the centripetal force applied by the tracks change by?

- A model train with a mass of #1 kg# is moving along a track at #4 (cm)/s#. If the curvature of the track changes from a radius of #160 cm# to #60 cm#, by how much must the centripetal force applied by the tracks change?
- A model train, with a mass of #3 kg#, is moving on a circular track with a radius of #4 m#. If the train's rate of revolution changes from #3 Hz# to #2 Hz#, by how much will the centripetal force applied by the tracks change by?
