Question

The Sun has an intensity of 1367 W/m² at a distance of 1 AU (1.5 x10¹1 m) from its surface. We are going to consider a solar sail that is perfectly absorptive and is a square measuring 20m by 20m, with a mass of 1.5 kg. a. What would be the acceleration of the sail near Earth? . What would be the acceleration of the sail at a distance of 2 AU from the Sun? c. How would your answer to part (a) change if the sail was instead made out of perfectly reflective material, assuming that it reflects all wavelengths of light? (Hint: Consider conservation of momentum and impulse!)
