A particle is moving in a straight line. The variation of position ‘x’ as a function of time ‘t’ is given as x = (t^3 – 6t^2 + 20t + 15) m. The velocity of the body when its acceleration becomes zero is :

To find velocity v, we first need the relation between v and t .

to know time for a=0 we need relation between a and t .
