When a force of $40\ N$ is applied on a body it moves with an acceleration of $5\ ms^{-2}$. Calculate the mass of the body.

Academic Physics NCERT Class 9

Here given, applied force $F=40\ N$

Acceleration $a=5\ ms^{-2}$

Therefore, the mass of the body $ m=\frac{F}{a}$

$=\frac{40\ N}{5\ ms^{-2}}$

$=8\ kg$

Therefore, the mass of the body is $8\ kg.$
