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

A 1 kilogram bead moves with constant total mechanical
energy on a frictionless wire track. The track is in a
vertical plane and consists of straight segments and
circular segments. For example, points B, F, G, H are on

segments. Point A is at the top of the track and point H
is the lowest point of the track.
The bead is shown initially at point C with a velocity 5.6
m/s down as represented by the velocity arrow. The
circular portion of track that includes points A, C, D has
a radius 3.2 meters.
