Differentiate the velocity with respect to time  and solve it by hit and trial... ÷*/¥¥*/%(%,*/(/*=,*=/¥*/,/*(*%/*(¥%(%

I think at the place of (t^2)/3 it should be (t^3)/3  . if it is then differentiate velocity with respect to time  then it forms quadratic whose roots are 2 and 3 ...so accel^n is negative in open interval 2 to 3
