Example 6.
A mass of 4 kg. is drawn across a rough horizontal table by means of
a string passing over a smooth pulley fixed at an edge of the table and supports a mass
of2 kg. at the other end. Ifthe coefficient of friction be 5/16, find the acceleration of the masses.

trolley of mass 20 kg is attached to a block of mass 4 kg by a massless string passing over a frictionless pulley as shown in the figure. If the coefficient of kinetic friction between trolley and the surface is 0.02, then the acceleration of the trolley and block system is:
(Take g = 10 ms
−2
)
