As we discussed in concept

Impulse -

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

astleft [ MLT^{-1} 
ight ]

- wherein

 

 Impulse = Change in momentum

I=mv-(-mv)=2mv

 


Option 1)

MV

This option is incorrect.

Option 2)

1.5MV

This option is incorrect.

Option 3)

2MV

This option is correct.

Option 4)

Zero

This option is incorrect.
