The velocityof a particle that moves in the positive X- direction varies with its position, as shown in figure-1.22. Find its acceleration in `m//s^(2)` where `x = 6m`

Options

A. `- 1.5 m//s^(2)`
B. `1.5 m//s^(2)`
C. `2 m//s^(2)`
D. `-2 m//s^(2)`

Answer

A

Explanation

`a = (vdv)/(dx) = 3 (-(1)/(2)) = -1.5 m//s^(2)`
