It has been proposed that a spaceship might be propelled in the solar system by radiation pressure, using a large sail made of foil. How large must the surface area of the sail be if the radiation force is to be equal to the Sun's gravitational attraction? Assume that the mass of the ship + sail is 1300 kg, that the sail is perfectly reflecting, and that the sail is oriented perpendicular to the Sun's rays. (With a large sail, the ship is continuously driven away from the Sun.)

The average atmospheric pressure on earth is approximated as a function of altitude by the relation patm = 101.325 (1 − 0.02256z)5.256, where patm is the atmospheric pressure in kpa, and z is the altitude in km with z = 0 at sea level. determine the approximate atmospheric pressures at atlanta (z = 306 m), denver (z = 1610 m), mexico city (z = 2309 m), and the top of mount everest (z = 8848 m).
