The complete sentence is: <span>Centrifugal force is a fictitious force that some people believe causes you to feel as if you are being pushed outward from the center of a circle while traveling in uniform circular motion.
In fact, centrifugal force is an inertial force: it is not a real force, but it is due to the fact that the reference frame is rotating. The real force in a uniform circular motion is the centripetal force, which pushes towards the centre of the circle, and keeps the object in circular motion.</span>
KE=1/2mv^2 - equation for kinetic energy KE=(1/2)(0.12 kg)((7.8 m/s)^2 - plug it into the formula KE=(0.06 kg)(60.84 m/s) - multiply 1/2 to the mass and square the speed KE= 3.7 J - answer Hope this helps
