Question

The variation of velocity of a particle moving along a straight line is shown in the figure. The distance travelled by the particle in 4 s is:

• A. 25 m
• B. 30 m
• C. 55 m
• D. 60 m

Answer 1

The correct option is C 55 m

Area of the Velocity-Time graph gives distance.

As shown on figure, Distance = Area of A + Area of B + Area of C + Area of D

$\Rightarrow$ Distance $=\frac{1}{2}\times 1\times 20+1\times 20+\frac{1}{2}\times 1\times 10+10\times 2=55m$
