This was a fun one, because it has been YEARS since I've done something like this. I did conceptual Physics in 2001, AP Physics in 2003, and Physics for three quarters in college in 2005, and then finished my Mechanical Engineering degree in 2010, but I haven't done a whole lot of this type of problem solving since. I had a very rough idea of the concepts going on here, and I recalled a few things from school, but I had to look up the moment of inertia equation for a solid cylinder, and I had to remind myself that Tau = I*alpha.
Initially, I had misread the problem to think that Mwheels was the weight of
each wheel, so my answer was 4 times too large, which I quicklyrevised.
Thanks for making me think on a Sunday morning.
