Question:

A small space telescope at the end of a tether line of length L moves at linear speed v about a central space station.
a. What will be the linear speed of the telescope if the length of the line is reduced to 0.33 L?
b. If the initial linear speed of the telescope is 1.0 m/s, what is its speed when pulled in to one-third its initial distance from the space station?
