Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

Question

Given a small disk (5-Kg) sliding on top of a smooth table which is connected to an elastic cord
having a tension of 10r N (r radial position of the small disk is in meters). If we gave the disk a
starting velocity of 6 m/s in the transverse direction when it is at r = 2 m, calculate:
a- the magnitudes of the radial and transverse components of its velocity when r = 4 m?
b- the maximum value of r reached by the disk.
