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 of 33 km/h is 1.6  10 6N, 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?
