frictionless platform

You stand on a frictionless platform that is rotating an angular speed of 1.50rev/s, Your arms are outstretched, and you hold a 3.00kg mass in each hand. The moment of inertia of you and the platform is 6.00 kg*m^2 and the masses are initially 0.400 m from the axis of rotation. You then pull the masses in until they are 0.100 m from the axis of rotation.
1) What is the resulting angular speed of the platform?
2) What is the change in Kinetic Energy of the system?
