The 05:30 flight to Malaga takes off with a mass, including fuel, passengers, luggage and crew, of 300 000 kg. The gravitational field strength is 10 N/kg. It climbs to an altitude of 1200 m. If the runway was at an altitude of 220 m, how much gravitational potential energy has it gained (to the nearest kilojoule)?

Answers
Mass = 300 000kgg = 10N/kgThe height the aeroplane climbed, ∆h = (1200 + 220) m= 1420mthen, P.Eg = mgh= 300 000*10*1420= 4 260 000 000 J= 4.26 × 10^6 KJ
