My Physics C class was given a lab today with little explanation, and many of us are having issues determining a solution.
We must find the masses of both objects m and M. We aren't allowed spring scales, springs, or scales. Using cameras, timers, and rulers, we must find the masses.
I've attempted to derive multiple equations for each mass with the kinematic equations, rotational kinematic equations, and energy equations, however when I use them in a system of equations, the masses always cancel out.
My next idea is to determine rotational momentum, convert the rotational momentum to linear momentum, and take the derivative to find force. I'm not really sure what force this is, but if I got that far I believe I could figure it out.
What am I missing? This seems like an odd problem or a trick question. Our physics teacher is known to throw stuff at us like this without a prepared solution, so I'm worried this is one of those times.
