3. A beam of light carries momentum and therefore the absorption of a beam of light results in animpulse. One could contemplate constructing a "solar sail" that catches light the way a regularsail catches wind. One could even imagine trying to escape the solar system this way.The sun has a mass of 2 x 100 kg and emits 4 x 102% W of power.a) If the sail absorbs all of the light that reaches it, what is the maximum surface density the sailconld have and still escape to infinity?b) What if the sail is a perfect reflector?c) How feasible do you think these quantities are?
