Question

a force of 20 N acts upon a body whose weight is 9.8N . what is the mass and acceleration produced in the body ?(g=9.8 m/s²)

Answer 1

$$\begin{gathered} \mathrm{Mass}\mathrm{of}\mathrm{the}\mathrm{body}: \\ \mathrm{m}=\frac{\mathrm{W}}{\mathrm{g}} \\ =\frac{9.8}{9.8} \\ =1\mathrm{kg} \\ \mathrm{Acceleration}\mathrm{produced}\mathrm{in}\mathrm{the}\mathrm{body}: \\ \mathrm{a}=\frac{\mathrm{F}}{\mathrm{m}} \\ =\frac{20}{1} \\ =20\mathrm{m}/{\mathrm{s}}^2 \end{gathered}$$
