A particle starts moving with initial velocity `3m//s` along `x`- axis from origin. Its acceleration is varying with `x` co-ordinate in parobalic nature as shown in the figure. At `x=1m `, tangent to the graph makes an angle `45^(@)` with positive `x`- aixs. Then at `x=3m`,

A

velocity of the particle is `3sqrt(2)m//s`

B

velocity of the particle is `3sqrt(2)m//s`

C

acceleration of the particle is `4.5m//s^(2)`

D

acceleration of the particle is `9m//s^(2)`
