2) For the following questions, start your analyses by considering at least Newton’s Law of Gravitation, centripetal acceleration, Kepler’s law or Energy Conservation. Take the Gravitational constant to be a) From Earth we can measure the radius of Mars using our telescopes. An estimate for it is By sending an exploratory robot to Mars, we determined the acceleration due to gravity on its surface as 3.73 m/s2. Estimate the mass of Mars. b) The Earth revolves around the Sun once a year at a distance of . Estimate the mass of the Sun. c) A rocket is launched straight up from Earth’s surface at 2100 m/s. By ignoring air resistance, determine the maximum height it reaches?
