a chemical centrifuge holds containers 55mm from the centre, and has an operating rotation speed of 5400 rpm. if a container is holding 15 grams of material, what is the centripetal force exerted on the container by the centrifuge
A typical laser disc can spin as fast 1800 RPM. The angular speed is therefore 2pi* 1800/60=60 pi rad/s. If it takes 17s to stop the rotation from this top speed, how much change is in angle displacement (i.e. The change in angle measured in radians)? Report the result in absolute value.
