Apossible means of space flight is to place a perfectly reflectingaluminized sheet into orbit around the earth and then use the lightfrom the sun to push this "solar sail." suppose a sail of area5.00 105 m2 and mass 6300 kg is placed in orbit facing the sun.(a) what force is exerted on the sail? n(b) what is the sail's acceleration? m/s2(c) what time interval is required for the sail to reach the moon,3.84 multiplied by 108 maway? ignore all gravitational effects, assume the accelerationcalculated in part (b) remains constant, and assume a solarintensity of 1370 w/m2.days

Yvette hangs a 2.4kg bird feeder in the middle of a rope tied between two trees. the feeder creates a tension of 480 n in each side of the the rope.
