The body moves along the `x-`axis . At time `t=0` the velocity of particle is `+0.5m//s`. The acceleration of particle in different time interval is given as`:`
`a={{:(-1 m//s^(2)," ",0slt=tlt=3s),(-2 m//s^(2)," ",3s lt tlt6s),(+4m//s^(2)," ",6s lt=tlt=10s):}`

A

The speed of particle at `t=6 s` is zero.

B

The speed of particle at `t=6s` is `6m//s`.

C

The speed of particle of at `t=10 s` is `25 m//s`

D

The speed of particle at `t=10s` is `12m//s`.
