Using astronomical data from Appendix F, along with the fact that the earth spins on its axis once per day, calculate

(a) The earth's orbital angular speed (in rad/s) due to its motion around the sun,

(b) Its angular speed (in rad/s) due to its axial spin,

(c) The tangential speed of the earth around the sun (assuming a circular orbit),

(d) The tangential speed of a point on the earth's equator due to the planet's axial spin, and

(e) The radial and tangential acceleration components of the point in part (d).
