A Possible Means of Spaceflight Is to Place a Perfectly

Short Answer

A possible means of spaceflight is to place a perfectly reflecting aluminised sheet into Earth orbit and use the light from the Sun to push this solar sail.If a huge sail of area 6.00 *105 m2 and mass 6000 kg were placed into orbit and turned toward the Sun, what would be the force exerted on the sail? (Assume a solar intensity of 1380 W/m2.)
