The velocity-time graph of a particle in straight line motion is velocity-time graph of a particle in straight line motion is shown in. The particle starts its motion from origin.
.
The distance of the particle from the origin after `8 s` is .

Options

A. `18 m`
B. `16 m`
C. `8 m`
D. `6 m`

Answer

a

Explanation

Distance covered=area of speed-time graph
`=(1)/(2) xx (45+2) xx 4+ (1)/(2) (4+2) xx 2 =18 m`.
