A body starts from the origin and moves along the X-axis such that the velocity at any instant is given by `(4t^3-2t)`, where t is in sec and velocity in m/s. what is the acceleration of the particle when it is 2 m from the origin?
A. `28 m//s^(2)`
B. `22 m//s^(2)`
C. `12 m//s^(2)`
D. `10 m//s^(2)`
