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
