A body of $5 \,kg$ is moving with a velocity of $20 \,m/s$. If a force of $100\,N$ is applied on it for $10\,s$ in the same direction as its velocity, what will now be the velocity of the body.........$m/s$

$v = u + at = u + \left( {\frac{F}{m}} \right)t = 20 + \left( {\frac{{100}}{5}} \right) \times 10 = 220\,\;m/s$
