Figure shows velocity time graph of a particle moving in straight line. Which of the following statement(s) is `/` are CORRECT`:-`

Options

A. Particle crosses its initial position
B. Speed of the particle Increases continuously
C. Acceleration of patticle is zero
D. At `t_(0)`,`(d|vec(V)|)/(dt)` of particle is zero.

Answer

A

Explanation

To cross intial position, displacement is zero then, area under graph must be equal. Form `O` to `t_(0)`, `V` decrease. Accerleration is equal to slope, which is constant.
At `t_(0)`, `(dv)/(dt)` is acceleration = slope `ne0`
