the largest passenger ship still in service is the ss norway, which has a mass of 7.6*10^7 kg. the force required to accelerate the ss norway from rest to its top cruising speed if 33 km/h is 1.6*10^6 N, assuming that this acceleration takes place over a distance of 2.0 km. How much work must be done on the ship during this period of acceleration

Awelder using a tank of volume 7.50×10^-2 m^3 fills it with oxygen (with a molar mass of 32.0 g/mol ) at a gauge pressure of 3.30×10^5 pa and temperature of 37.1 ∘c. the tank has a small leak, and in time some of the oxygen leaks out. on a day when the temperature is 23.1 ∘c, the gauge pressure of the oxygen in the tank is 2.00×10^5 pa . a) find the initial mass of oxygen. b) find the mass of oxygen that has leaked out.
