Vedclass · Answer

(A) According to Newton's second law of motion,the force applied to an object is equal to the rate of change of its momentum.Mathematically,the force $F$ is given by the ratio of the change in momentum $\Delta P$ to the time interval $\Delta t$:$F = \frac{\Delta P}{\Delta t}$Given:Force $F = 2 \ N$Change in momentum $\Delta P = 0.4 \ kg \ m \ s^{-1}$Rearranging the formula to solve for time $\Delta t$:$\Delta t = \frac{\Delta P}{F}$Substituting the given values:$\Delta t = \frac{0.4}{2} = 0.2 \ s$Therefore,the time taken is $0.2 \ s$.

The time taken by a force of $2 \ N$ to produce a change of momentum of $0.4 \ kg \ m \ s^{-1}$ in a body is: (in $s$)
