Solve the problem.Show that a planet in a circular orbit moves with constant speed.
What will be an ideal response?
Kepler's first law says that the eccentricity of a planet's elliptical orbit e = 
-1. The eccentricity of a circle is 0, and solving for the speed v0 with e = 0 gives v0 = 
. Since r0 is a fixed radius for a circular orbit, all three terms for computing v0 are constant, so v0 is also constant.
