Question

A block of mass 40 kg slides over a surface, when a mass of 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 0.02. The acceleration of block is. $\left(\right.$ Given $\left.\mathrm{g}=10 \mathrm{~ms}^{-2}\right)$

Select the correct option:

A

$1 \mathrm{~ms}^{-2}$

B

$1 / 5 \mathrm{~ms}^{-2}$

C

$4 / 5 \mathrm{~ms}^{-2}$

D

$8 / 11 \mathrm{~ms}^{-2}$

✓ Correct! Well done.
