A large cruise ship of mass 6.80 x 107 kg has a speed of 12.8 m/s at some instant. (a) What is the ship's kinetic energy at this time? (b) How much work is required to stop it? (Include the sign of this value.) (c) What is the magnitude of the constant force required to stop it as it undergoes a displacement of 3.60 km?
The weight of the atmosphere above 1 m^2 of Earth's surface is about 100,000 N. Density of course, become less with altitude. But suppose the density of air were a constant 1.2 kg/m^3. Calculate where the top of the atmosphere would be.
