The radius of the earth's orbit around the sun (assumed to be circular) is 1.50 x 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 x 10^7 km, orbital period = 88.0 days)?
D) What is the radial acceleration of the Mercury?
