A block of mass $\displaystyle 40$ kg slides over a surface, when a mass of $\displaystyle 4$ kg is suspended through an inextensible massless string passing over frictionless pulley as shown below.
The coefficient of kinetic friction between the surface and block is $\displaystyle 0.02$ . The acceleration of block is. (Given $\displaystyle \mathrm{g}=10 \mathrm{~ms}^{-2}$.)
Official answer
(4)
$\displaystyle 8 / 11 \mathrm{~ms}^{-2}$
