Vedclass · Answer

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 $=\frac{2}{2}=1 m / s$

${ Final velocity } =-\frac{2}{2}=-1 m / s$

$\overrightarrow{{ P }_{i}} =0.4 N - s$

$\overrightarrow{ P_f } =-0.4 N - s$

$\overrightarrow J =\overline{ P }_{f}-\overline{ P }_{i} =-0.4-0.4=-0.8 N - s ( J = impulse )$

$|\overrightarrow J |=0.8 N - s$
