문제) A possible means of space flight is to place a perfectly reflecting aluminized sheet into orbit around the Earth and then use the light from the Sun to push this “solar sail.” Suppose a sail of area A = 6.00 × 10^5 m^2 and mass m = 6.00 × 10^3 kg. Ignore all gravitational effects and assume a solar intensity of 1370 W / m^2 (a) Calculate the force is exerted on the sail.(b) Calculate the sai..
