Question

A particle moves in a circular orbit about the earth and directlyover the equator.
1) Calculate the work done by gravity during one orbit of theparticle about the earth.
2) The particle has a period of 24 hours. Calculate the radius ofthe orbit.
3) The particle has a period of 24 hours. Calculate theacceleration due to gravity at this point without reference toNewton’s Universal law of gravitation.
4) The particle has a period of 24 hours. Calculate theacceleration due to gravity at this point using Newton’s Universallaw of gravitation?
5) What is the angular velocity across the sky as observed by aperson in the Rochester city?
