A plane is fitted with pontoons for operation on lakes. As it taxies out for take-off, the plane itself weighs 10670 Newtons (2849lbs), it has 40 gallons of gasoline in its tanks, and the pilot and passenger together weigh 1513 Newtons (340 lbs). One gallon of gasoline weighs 25 Newtons (5.67lbs). What is buoyant force on the plane when it floats in a body of water?
Take the mass density of water to be 1000 kg/m3 and the acceleration due to gravity as 9.8 m/s2
what volume of water do the pontoons displace?
