The radius of the earths orbit around the sun assumed to

Question

The radius of the earth's orbit around the sun (assumed to becircular) is 1.50 108 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?

m/s

(b) What is the radial acceleration of the earth toward the sun inm/s2?

m/s2

(c) Repeat parts (a) and (b) for the motion of the planetMars (orbit radius = 2.28 108 km, orbitalperiod = 687.0 days).
