A frictionless cylindrical flywheel, of diameter 250mm and mass 30kg, has a string attached/wrapped on the outside diameter, with a mass of 10kg on the other end.
What is the radius of gyration of the flywheel?
If the mass starts 1.5m form the floor, what will its speed be when the mass is released & it hits the floor? and at this point how much rotational kinetic energy will the flywheel have?
Any hints or answers would be gratefully received.
many thanks
Greg
