Sorry for the late reply. I was gone for the weekend. There was a diagram included and I have included it in this post. It appears to me that while it is a solid cylinder, the information about how the mass is distributed across two sections of different radii is excluded.

Homework Statement So I generally understand how to solve the following problem. My only roadblock is that I am not sure I am solving the moment of Inertia correctly. I know that for a solid cylinder you would use I = 1/2mr^2, but I am not sure how if it has only one mass given of 10 kg, yet...

The way it turns out 1.92m/0.54s = 3.55m/s, multiply that by 2 and you get 7.1m/s. If you set vf = gt then it is 9.8 x .54 which results in 5.29m/s. This difference just seemed so large to me, but the first equation assumes everything is done very accurately, while the second equation does not...

You are correct, it was freefall using a volleyball. Sorry, I should have included that information. I am assuming the numbers were so off due to experimental error with the timing. Thanks so much for your help.

Homework Statement Shouldn't average velocity multiplied by 2 be equal to final velocity. We were doing a lab and we calculated an average time of .54 seconds to travel 1.92 meters. Multiplying the average velocity by 2 gives an extremely different answer than vf=gt. I know there is...
