A 2.00Kg puck on a frictionless horizontal surface on the Earth is constrained to a circular orbit by a 4.00 meter long string attached to a vertical rod. Assume the string is attached to the rod by a ring that lets it revolve around the rod without friction. The string can withstand up to a 50.0N tension without breaking. Once the puck is released, it slides on a horizontal dirt surface with a coefficient of kinetic friction of 0.15. How far will it go to where it stops and how much time does it take to stop?

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.
