The supersonic aircraft Concorde has a length of 62.2m when sitting on the ground on a typical day when the temperature is 12.0 oC . The Concorde is primarily made of aluminum. In flight at twice the speed of sound, friction with the air warms the Concorde's skin and causes the aircraft to lengthen by 30.0cm . (The passenger cabin is on rollers, so the airplane expands around the passenger cabin.) Take the coefficient of linear expansion for aluminum to be a = 2.40×10?5/oC. *Note in the last equation it is 10 to the negative 5th power, not just minus 5* What is the temperature of the Concorde's skin in flight?
