Question

The figure shows the position - time (x - t) graph of one-dimensional motion of a body of mass 0.4 kg. The magnitude of each impulse is (A) 0.4 Ns (B) 0.8 Ns (C) 1.6 Ns (D) 0.2 Ns

From the graph, it is a straight line so, uniform motion. Because of impulse direction of velocity changes as can be seen from the slope of the graph.
Initial velocity

= \frac{2}{2} = 1 m / s

Final velocity

= - \frac{2}{2} = - 1 m / s

P_{i} = 0.4 N - s

P j_{i} = 0.4 N - s

J = P_{f} - P_{i} = - 0.4 - 0.4 = - 0.8 N - s

(

J

= impulse)
