As we discussed in concept

Impulse -

vec{I}=int_{t_{1}}^{t_{2}}vec{F}cdot dt

astleft [ MLT^{-1} ight ]

- wherein

 

 Change in momentum

\Delta P=\int F.dt\:\:\:=Area\:of\:F-t\:graph

Area of \Delta - area of rectange + area of rectange

\Delta P = \frac{1}{2}\times 2\times 6-3\times 2 + 4\times 3\:=\:12N.S

This option is incorrect.

Option 3)

12Ns

This option is correct.

Option 4)
