1.) If a planet goes faster (v large) when it is closer to the sun, what happens to the centripetal acceleration as the planet nears the sun? 2.) K for objects orbiting the Sun is 2.99 x 10^-19 s^2/m^3. It takes the earth 365 days to revolve around the sun. (1 day = 86400s) Calculate the mean orbital radius for Earth.
