Europa orbits Jupiter at a distance of 6.7 x 108 m from Jupiter's cloudtops
(the surface of the planet). If Jupiter's mass is 1.9 x 1027 kg and radius is
6.8 x 107 m, what is the speed of Europa as it orbits in m/s?
Round to the nearest hundredth. Don't worry about putting units, just put
the number.
A comet is in an elliptical orbit around the Sun. Its closest approach to the Sun is a distance of 5.0 × 1010 m (inside the orbit of
Mercury), at which point its speed is 9.6 x 104 m/s. Its farthest distance from the Sun is far beyond the orbit of Pluto. What is its speed
when it is 6 x 1012 m from the Sun? (This is the approximate distance of Pluto from the Sun.)
