Two satellites are launched at a distance R from a planet of negligible radius. Both satellites are
launched in the tangential direction. The ﬁrst satellite launches correctly at a speed v0 and enters
a circular orbit. The second satellite, however, is launched at a speed
v0. What is the minimum
distance between the second satellite and the planet over the course of its orbit?
Where you wrote:
is that supposed to be (v0/2) ?
If so, the second satellite does not have sufficient kinetic energy to maintain a circular orbit at distance R.
