Callisto orbits Jupiter at an average distance of 1.88
106 km with an orbital period of 0.0457 yr. The
Moon, which is one of the satellites of the Earth, orbits its parent at an average distance of 3.84
with an orbital period of 0.07481 yr.

(a) Use the above information to find the orbital speeds of Callisto around Jupiter and of the Moon around
the Earth.
vCallisto = 8190
m/s
vMoon = 1021
m/s
(b) What is the expression for the mass M of the parent in terms of the orbital speed v of the satellite,
the orbital radius R of the satellite and the gravitational constant G? (Do not substitute numerical
values; use variables only.)

A geosynchronous Earth satellite is one that remains above the same point on Earth (provided it orbits in
the equatorial plane in the same direction as Earth's rotation). Such orbits are useful for communication
and weather observation. Calculate the radius, in meters, of such an orbit.

Two planets P1 and P2 orbit around a star S in circular orbits with speeds v1 = 40.8 km/s, and
v2 = 58.2 km/s respectively.
(a) If the period of the first planet P1 is 720 years what is the mass, in kg, of the star it orbits around?

The gravitational force of the star on the planet supplies the centripetal force needed to keep the
planet in its circular orbit. kg
