the radius of the earth's orbit around the sun(assumed to be circular) is 1.50 x 10 power of 8km, 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, in m/spower of 2?
c)repeats part (a) and (b) for the motion of the planet Mercury (orbit radius = 5.79 x 10 power of 7km, orbital period = 88 days?
