(C) Impulse is defined as the area under the force-time $(F-t)$ graph.For figure $(I)$ (Rectangle): $	ext{Area} = 	ext{base} 	imes 	ext{height} = 1.0 	imes 0.25 = 0.25 	ext{ units}$.For figure $(II)$ (Triangle): $	ext{Area} = \frac{1}{2} 	imes 	ext{base} 	imes 	ext{height} = \frac{1}{2} 	imes 2.0 	imes 0.3 = 0.3 	ext{ units}$.For figure $(III)$ (Triangle): $	ext{Area} = \frac{1}{2} 	imes 	ext{base} 	imes 	ext{height} = \frac{1}{2} 	imes 1.0 	imes 1.0 = 0.5 	ext{ units}$.For figure $(IV)$ (Triangle): $	ext{Area} = \frac{1}{2} 	imes 	ext{base} 	imes 	ext{height} = \frac{1}{2} 	imes 1.0 	imes 1.0 = 0.5 	ext{ units}$.Comparing the areas,the impulse is highest for figures $(III)$ and $(IV)$.

Figures $I, II, III$ and $IV$ depict the variation of force with time. In which of these situations is the impulse the highest?
