Question

# The velocity-time graph of a body moving in a straight line is shown. The displacement of the body in 10s is ?

A
4m
B
6m
C
8m
D
10m

Solution

## The correct option is B $$8 m$$The displacement of the body in $$10sec$$ is area under the velocity-time graphFor $$t=0sec\, to\, 8sec$$$$s_1=\dfrac{1}{2}\times 4\times 2+\dfrac{1}{2}\times 2\times 2+\dfrac{1}{2}\times 2\times 2$$$$S=4+2+2=8m$$For $$t=8sec$$ to $$t=10sec$$$$s_2=0$$Total displacement is $$8m$$.The correct option is C.Physics
