6 ms^-1  .

Given:

• force acting on a body of mass 2 kg.

To Find:

• impulse of force and final velocity of force .

Solution:

Impulse = area under F-t graph

m ( υ − u ) = ( 4 × 2 / 2 ) + 4 × 1 + ( 4 × 2 ) / 2

                = 12 N − s

2 ( υ − 0 ) = 12 ,

             υ = 12 / 2

                 = 6 $m s ^{-1}$

Thus the answer is  6 $m s ^{-1}$. [6 ms^-1]
