Question : A particle 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 second and velocity is in ms^(-1). What is the acceleration of the particle when it is 2 m from the origin?

(A) $10ms^{-2}$

(B) $12ms^{-2}$

(D) $28ms^{-2}$

Answer : option (C)

Solution :

A particle 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 second and velocity is in ms^(-1). What is the acceleration of the particle when it is 2 m from the origin?
