A can of soup has a mass 420 g, height 13 cm, and diameter 5.6 cm. It is placed at rest on the top of an incline that is 3 m long at 22 degrees to the horizontal. The acceleration of gravity is 9.8 m/s^2. Calculate the moment of inertia of the can if it takes 1.5 s to reach the bottom of the incline.
