The moment of inertia for a set of objects of mass m; rotating about a common axis is defined as 1 = Σm₁r? 2 where r, is the distance of the ith object to the axis of rotation. If there are many particles that make up a larger object then this sum transforms into an integral, 4-fff or a. I = dV, V where p is the mass density and V the volume of the object. In this exercise we will explore moment of inertia by rolling two objects down an incline plane in the Experimental Math Lab Space.

A can full of soda (total mass is about 375 g, where 355 g comes from the liquid and 20 g from the aluminum can, radius is about 33 mm) is released on a slope. The slope has an angle of 30° of inclination and a length of 40 cm. Due to friction, the can roll over the slope without slipping. Determine the time it takes for the can to reach the bottom of the slope.Repeat the calculation for the empty can (m = 20 g and R = 33 mm). Note: In both cases, ignore the contribution from the top and bottom metallicparts of the can (disks) to the moment of inertia.
