Apossible 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 = 5.50 105 m2 and mass m = 6.70 103 kg is placed in orbit facing the sun. ignore all gravitational effects and assume a solar intensity of 1 370 w/m2. (a) what force is exerted on the sail? n (b) what is the sail's acceleration? µm/s2 (c) assuming the acceleration calculated in part (b) remains constant, find the time interval required for the sail to reach the moon, 3.84 108 m away, starting from rest at the earth. days
