Problem

Two blocks of masses

3\,\text{kg}

and

2\,\text{kg}

are tied together by a light string and placed on a horizontal surface where the coefficient of kinetic friction for both blocks is

\mu_k = 0.20

. A horizontal force of

15\,\text{N}

is applied to the

3\,\text{kg}

block. Taking

g = 10\,\text{m\,s}^{-2}

, calculate: (i) the acceleration of the system, (ii) the tension in the string connecting the blocks.
