Question: The radius of the earth's orbit around the sun (assumed to be circular) is 1.5*10^8 km , and the earth travels around this orbit in 365 days.
a) What is the magnitude of the orbital velocity of the earth in m/s?
b) What is the radial acceleration of the earth toward the sun?
c) What is the magnitude of the orbital velocity of the planet Mercury (orbit radius= 5.79*10^7, orbital period = 88.0 days)?
d) What is the radial acceleration of the Mercury?
