time wn a=0 is t=T
so u need to find vavg in intevral t=0 to t=T
so vavg=(dist covered)/T
now find distance covered
on integration v=∫a(t)dt
v=∫a(0)(1-(t/T))dt (take limits from 0 to v on LHS and o to t on RHS)
=a(0)(t-(t)2/2T)
s=∫vdt
=∫a(0)(t-(t)2/2T)dt
=a(0)(t2/2-t3/6T) (take limits from 0 to s on LHS and o to T on RHS)
=a(0)(T2/2-T3/6T)
=a(0)T2/3
so now vavg= s/T
=a(0)T/3
PLZ APPROVE IF USEFUL and in case of further doubts ask in ans box
