Connected Particles - Rough Inclined Plane
In this example I show you how to handle a problem where two particles are connected by a string passing over a pulley on a rough inclined plane.
A particle A of mass 2 kg is attached by a light inextensible string, passing over a smooth pulley to a particle B of mass 4 kg as shown in the diagram. A rests on a rough plane inclined at 30° to the horizontal.
If the particles are released from rest and the coefficient of friction between A and the plane is 0.4, find: (i) the acceleration of A, (ii) the tension in the string.
