A disk rolls down a slope. It rotational axis is its center of mass. It is rotation at a constant angular speed making 34.0 full revolutions in a time interval of 3.30 s.

1)What is the rotational inertia of the disk if its mass is 11.7 kg, and its radius is 49.6 cm?

A=1.44kmg^2

2) What is the rotational kinetic energy K of the rotating wheel?

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

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