1) A small spaceship cruises the solar system using an ideal, square absorbing solar sail with side length L = 1000 m.
a. Assume the sun can be modeled as a point source of light. If the intensity of electromagnetic radiation near the earth is 1300 W/m^2 , and the earth is 150×10^9m from the sun, what is the power of the sun’s light emission? If this spacecraft is close to Mars, 230×10^9m away from the sun, and is traveling directly away from the sun with an acceleration a0 = 0.01m/s^2 what is the mass of the spacecraft?
b. You fasten two adjustable light polarizers with polarizer axes that subtend an angle θ with respect to one another on the side of the sail where light is incident. These polarizers are the same size as the sail, covering its total area. What must θ be to reduce the acceleration of the craft to a0/8? What must θ be to reduce the acceleration of the craft to 0?
