The velocity time graphs of a body is as shown. The displacement suffered by it is

A)  300 m                  

B)  400 m

C)  250 m  

D)  200 m

Correct Answer: C

Solution :

  \[\because \]velocity\[\times \]Time Displacement Displacement is area under velocity time graph. Area of\[\Delta ABC\frac{1}{2}\times 10\times 10=50m/s\] Area of square BCDE \[10\times 10=100\,m/s\] Area of \[\Delta DEF\frac{1}{2}\times 20\times 10=100\,m/s\] \[50+100+100=250\,\,m/s\]
