a.) The mean solar distance of Mercury is 0.387 Au. What is its period? b.) Suppose two planets A and B revolve around the same star in circular orbits. The distance of A from the star is twice that of B, the mass of B is three times the mass of A. Find the ratio of the gravitational force exerted by the star on the two planets. c.) What is the escape speed from planet Earth given that the mass of Earth is 6 x 1024 kg and its radius is 6.4 x 106 m? Title: Re: Problem solving. Show complete solutions.
