From the graph we can say, upto t = 2.0 s, the body moves with a constant velocity
Slope of position-time graph =

4

2

= 2 m/s
After t = 2.0 s, position-time graph is parallel
to time axis i.e., body comes to rest.
∴ Change in velocity = dx = 2 m/s
Impulse = Change in momentum = mdv = 0.1 x 2 = 0.2 kg m/s
