A meteor that falls to earth from a great distance has a speed of 11 km/s. In class we found that the temperature of an iron meteor is 290,000K. We assumed all of the energy heats the meteor and none of it is transferred to the surroundings. a)Collect your ideas on physics. Read parts (b)-(d). What physics applies. b) If the meteor is made of calcium , what is the speed of the meteor? Explain. c)If the temperature of the meteor is made of calcium and the same assumptions hold, what is the temperature of the meteor?Explain. d) Does the composition of the meteor make a big difference in the temperature. Explain.
