Two small balls P and Q, of masses 3 kg and 2 kg respectively, are attached to the ends of a light inextensible string. The string passes over a smooth fixed pulley. The balls are held at a height of 4 m above a horizontal floor, with the string taut. The parts of the string whic…

Two balls P and Q have masses 0.6kg and 0.4kg respectively. The balls are attached to the ends of a string. The string passes over a pulley which is fixed at the edge of a rough horizontal surface. Ball P is held at rest on the surface 2m from the pulley. Ball Q hangs vertically…

A train consists of an engine A of mass 50000kg and a carriage B of mass 20000kg. The engine and carriage are connected by a rigid coupling. The coupling is modelled as light and horizontal. The resistances to motion acting on A and B are 9000N and 1250N respectively (see diagram…
