A triangular wedge 6 m high, 12 m base length, and with a 13 kg mass is placed on a frictionless table. A small block with a 9 kg mass (and negligible size) is placed on top of the wedge as shown in the figure below. All surfaces are frictionless, so the block slides down the wedge while the wedge slides sidewise on the table. By the time the block slides all the way down to the bottom of the wedge, how far deltaXwedge does the wedge slide to the right in m?

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.
