A JET PLANE WHICH WEIGHT 29430 N AND HAS A WING AREA OF 20 M² FLIES AT A VELOCITY OF 250 KM/HR. WHEN THE ENGINE DELIVERS 7357.5 KW, 65% OF THE POWER IS USED TO OVERCOME THAT DRAG RESISTANCE OF THE WING. CALCULATE THE CO-EFFICIENT OF LIFT AND CO-EFFICIENT OF DRAG FOR THE WING. TAKE DENSITY OF AIR EQUAL TO 1.21 KG/M³.
