A metal can containing condensed mushroom soup has mass 210 g, height 11.6 cm and diameter 6.38 cm. It is placed at rest on its side at the top of a 3.00-m-long incline that is at 30.0° to the horizontal and is then released to roll straight down. It reaches the bottom of the incline after 1.50 s. Assuming mechanical energy conservation, calculate themoment of inertia of the can. Which pieces of data, if any, are unnecessary for calculating the solution.
