A couple of astronauts agree to rendezvous in space after hours. Their plan is to let gravity bring them together. She has a mass of 66.0 kg and he a mass of 70.0 kg , and they start from rest 21.0 m apart. Part A Find his initial acceleration Part B Find her initial acceleration Part C If the astronauts' acceleration remained constant, how many days would they have to wait before reaching each other? (Careful! They both have acceleration...
A possible 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 = 6.40 x 105 m2 and mass m = 7,100 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 in N) is exerted on the sail? (Enter the...
