A block of mass $10\, kg$ is placed on a rough horizontal surface having coefficient of friction $\,\mu = 0.5$. If a horizontal force of $100\, N$ is acting on it, then acceleration of the block will be ....... $m/s^2$

A block of mass $10\, kg$ is placed on a rough horizontal surface having coefficient of friction $\,\mu = 0.5$. If a horizontal force of $100\, N$ is acting on it, then acceleration of the block will be ....... $m/s^2$
$$ $a = \frac{{{\rm{Applied\, force - Kinetic \,friction}}}}{{{\rm{mass}}}}$ $ = \frac{{100 - 0.5 \times 10 \times 10}}{{10}} = 5m/{s^2}$
