On the line right before you started doing Conservation of Energy, it looks like you forgot to make the I1 and I2 terms positive.

When you are making your EOM through Newtonian I think the I1 and I2 terms in the final equation should be positive not negative? Our lecturer said that all of those terms should always be positive?

When you're plugging the numbers in for your differential equation, when I do both masses in snails i get -1.047 for the second part of the equation instead of -12.6, it seems that -12.6 comes about if you do the masses in slugs, but the other part is still in snails, is this just an error or is there a reason for it?

What are you using for $g$? Since we're in the Inch-Pound-Second system I opted to use $g=386.4 \frac{\text{in}}{\text{s}^2}$.
