Question

Velocity-time (v-t) graph for a moving object is shown in the figure. Total displacement of the object during the time interval when there is non-zero acceleration and retardation is\

Professor PC Thomas Classes · Answer

Between time interval 20s to 40s there is nonzero acceleration and retardation.\ $	herefore$ Displacement during this interval\ $=$ area between interval 20s to 40s\ $=\frac{1}{2} 	imes$ base $	imes$ height + area of rectangle\ $=\frac{1}{2} 	imes 20 	imes 3+20 	imes 1=30+20=50 \mathrm{~m}$\
