I am having trouble understanding how to solve this problem. Question: Suppose a man has a mass of 76kg and a density of 0.92g/cm3.
A) Calculate his volume.

b) Calculate the mass of air that he displaces, using the density of air from Table 5.2. The density of air is 1.29kg/m3

c) Calculate the buoyant force on him due to the air he displaces and compare this to his weight in newtons.

A1000-kg car is moving at 30 m/s around a horizontal unbanked curve whose diameter is 0.20 km. what is the magnitude of the friction force required to keep the car from sliding?
