1) An altimeter is a device that measures the height of a plane above the ground. It works based on air pressure according to the formula h = 18400log where h is the height above the ground in metres, P is the air pressure at that height, and Po was the air pressure on the ground at takeoff. Air pressure is measure in kilopascals (kPa). a) Air pressure on the ground was 102 kPa. If the airplane instruments measure a pressure of 32.5 kPa outside the plane, what is the height of the airplane to the nearest metre? (4 marks)
