Two blocks are linked by a massless cord that passes through the center of a rotating turntable, as shown in the diagram. The blocks have masses M1 = 1.3 kg and M2 = 2.4 kg. Block 1 rests a distance r = 0.34 m from the center of the turntable.With that being said, The coefficient of static friction between block and turntable is μs = 0.58. Block 2 hangs vertically below. 1)  Find the speed of circular motion at which block 1 just begins to slip outward along the surface of the turntable. Enter your answer in meters per second

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.
