2. The radius of the Earths very nearly circular orbit around the sun is 1.5x10^11 m
A) find the magnitude of the earth velocity as it travels around the sun (assume a year of 365 days)
B) Find the magnitude of the earths angular velocity as it travels around the sun (assume a year of 365 days and answer should be in s^-1)
C) Find the magnitude of the earths centripetal acceleration as it travels around the sun (assume a year of 365 days and the answer should be in m/s^2)
