A spacecraft is powered by a solar sail which has a total cross-sectional area A of 4.00E5m^2, and a total mass of 1.50E4 kg. Assuming the solar sail is pointed so that its axis is parallel with the radius-vector from the sun, and that it is perfectly reflective, what acceleration will the spacecraft exerpience if it is at the distance from the sun as planet Mercury? Assume the luminosity of the sun Lsun=3.839E26W, and the radius of Mercury’s orbit RMerc=5.79E10m.
