Hey, thanks both you guys for trying to help. I DID get rid of mass m when I set mCchangeT equal to 1/2mv^2, but still did not find the right answer (the book actually gives the answer of maximum temperature change of 0.15 Kelvin, but not much help in showing how to get there.) It seems like it...
Thank you for the reply, but I still can't get rid of the mass m in kinetic energy. I've tried using Work = change in KE = - change in potential energy and STILL this mass m is there. Can anyone help?
Homework Statement
Wind (dry air, so R=287 Jkg^-1K^-1) is moving isobarically along a flat surface at 30m/s. It hits a forest and 3/4 of its kinetic energy is transformed into heat energy by friction. What is the maximum temperature increase that could occur?
