Homework Statement
A metal can containing condnsed mushroom soup has a mass of 215g, a height of 10.8cm and a diameter of 6.38cm. It is placed at rest on its side at the top a 3.00m long incline that is at 25.0 degrees to the horizontal and is then released to roll straight down. Assume energy conservation, calculate the moment of interia of the can if it takes 1.50s to reach the bottom of the incline. Which pieces of data if any are unnecessary for calculating the solution
Homework Equations
[tex]I = \sum mr^2[/tex]
The Attempt at a Solution
This is what i have done, however it is incorrect.
[tex]I = \sum 0.215kg * 0.0319^2[/tex]
[tex]2.19 * 10^{-4}[/tex]
P.S
