A model train with a mass of #5 kg# is moving along a track at #16 (cm)/s#. If the curvature of the track changes from a radius of #88 cm# to #28 cm#, by how much must the centripetal force applied by the tracks change?
Assuming constant velocity and mass.
The change in force is equivalent to the force being applied currently subtracted from the force that will be applied.
Physics is always in Kilograms, Meters, and Seconds . So convert.
Use the equation to plug into our formula for
