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

Tsunamis are fast-moving waves often generated by underwater earthquakes. in the deep ocean their amplitude is barely noticeable, but upon reaching shore they can rise to an astonishing height of a six-story building. one tsunami generated off the aleutian islands in alaska, had a wavelength of 897km and traveled a distance of 3280km in 4.18h. (a) what was the speed (in m/s) of the wave? find the waves (b) frequency and (c) period.
