Question

A block of mass 3kg is connected to one end
of a massless string whose other end is
connected to a trolley of mass 20kg after
passing over a frictionless pulley as shown in
figure. If the coefficient of kinetic friction
between the trolley and the surface is 0.04
calculate the acceleration of the block and
the tension in the string. Given g=10m/s^2
