Ok, I'll talk to the professor. Thank you!

##e## is emissivity ##\sigma## is the Stefan-Boltzmann constant, ##5.67*10^{-8} W m^{-2} K^{-4}## A is the surface area T is the temperature ##\frac{dQ}{dt}## is the rate of heat transfer or radiated power At first glance this appeared to be an easy problem, just plug in the values and go, so...

I did some algebra and got the final equation mgh=1/2MR^2omega^2+1/2(2/5MR^2)omega^2, then plugged in the numbers and got an omega value of 111.09. Using 1.7 as h instead of cos(17)*1.7=1.63 I got 114.09. Both answers were wrong. Am I missing something, or did I just screw up the math?
