Physics students do an expriment to determine the coefficient of kinetic friction between a wooden object and the horizontal table it is on. This object has a mass of 1.6 kg. The students push it against a spring, which compresses the spring by 18cm. When released, the spring sends the object moving across the table and it stops 82 cm from where it was released. The spring constant is 200 N/m. Find the obeject-table coefficient of kinetic friction.

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.
