A 670 kg meteorite happens to be composed of aluminium. When it is far from the earth, its temperature is -15^@C and it moves with a speed of 14 kms^(-1)relative to the earth. As, it crashes into earth, let total energy is equally shared between planet and meteorite. Specific heat of liquid and gaseous aluminium be 1170 J kg^(-1)C^(-1).The final temperature of meteorite is (x + 0.87)104^(4@)""^@C . Find .x.
