A disk rolls down a slope. It rotational axis is its center of mass. It is rotation at a constant angular speed making 42.0 full revolutions in a time interval of 4.50 s.

(1) What is the rotational inertia of the disk if its mass is 15.1 kg, and its radius is 44.0 cm?

(2) What is the rotational kinetic energy of the rotating wheel? (answer in Joules)

(3) What is the translational kinetic energy of the rolling disk?

(4) What is the total kinetic energy of the rolling disk?
