A small ball of mass 740.0 g is placed in a tube that is bent into a circular arc of radius R= 67.5 cm. The friction between the ball and the walls of the tube is negligible. The ball has an iron core. A magnet is used to raise the ball until it makes an angle of 5.00 degrees with the vertical, and then released from rest. What will the ball’s velocity and acceleration be at this time?

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.
