2nd derivative mean u have to find velocity on time 2 ,3,4,5,6,7,8 whether it i positive or negative or zero ok now take out ur pencil see the graph at poition 2 put ur pencile in the shape of curve u will fine u move ur pencil clockwise means it is +ve

ok no prob u have to do this same way but thiking logically by comparing it with velocity like in position in time 2 sec u fine velocity in +Ve mean velocity is incereasing and if velocity is increasing then acc muts be +Ve

u see till 5sec velocity is increaing means till 5ec acceleration is +Ve but on 5 velocity is constant mean acceleration is zero and then from 6 veolcity is drceasing mean der must be deacceleration so accleration must be ve
