A particle starts moving from origin O along x axis. The velocity-time graph of motion of particle is given below. The positive values of v refer to direction of motion along +x axis, and the negative values of v refer to direction of motion along -x direction. Choose the correct statement(s).

A

Initial acceleration of the particle is $$4\,m/s^2$$

B

The displacement of particle from origin is 130 m after 16 second

C

Average speed of the moving particle during $$0\text{ to }16\,s$$ is 11.88 m/s

D

Somewhere during the motion for $$0\text{ to }16\,s$$, the retardation of the particle is $$10\,m/s^2$$
