Question:
Nasimiyu stands at the centre of a rotating platform that has frictionless bearings. She has a 2kg object in each hand, held 1m from the axis of rotation of the system. The system is initially rotating at 10rpm. Determine
i. The angular velocity of the system in radius per second after the objects are brought to a distance of 0.2m from the axis of rotation (10 marks)
ii. The change in rotational kinetic energy of the system as the objects are pulled closer to the centre of rotations (10 marks)
