till 2 sec, dv/dt is 5. So S1=1/2at^2 = 10m. Since vel is inc at constant rate it will b a parabola. After that till 4 sec, graph will b inclined at 45 degree. Then again the first part and finally u can draw it.

@ aspire for more i think ur wrong...

becoz the graph has different phases....

accelerated..then constant velocity ..then again acclerated and then retarded.......

and after retardation..it doesn't acclerated in -ve direction...so it stops there only...

hope i m correct....

the correct graph is this one only if body starts from rest......

velocity zero doesn't means that displacement is zero....

displacement may be non zero.....

plz rate....
