Finding out force from a relation of position

  1. Jun 30, 2017 #1
    1. The problem statement, all variables and given/known data

    A particle of 1kg loves along x acid such that it's position x varies with time t as x =t(t-1)(t-2) m find the force exerted on the particle at t=0,1,2
    2. Relevant equations
    Just given that position x varies with time t as x=t(t-1)(t-2)

    3. The attempt at a solution
    After opening the bracket, i tried to differentiate it twice to get relation of acceleration but the answer i m getting is incorrect...I m getting a=4t-6 am i correct?
