A particle accelerates from rest at a constant rate for some time and attains a velocity of 8m/s. Afterwards it deaccelerates with the constant rate and comes to rest .If the total time taken is 4sec, what is the distance travelled?

{ { \underbrace{ \mathbb{ \red{GiVeN\ }}}}}

GiVeN

Initial \:velocity(u) =0m/sInitialvelocity(u)=0m/s

Final\:velocity (v) =8m/sFinalvelocity(v)=8m/s

Time\: taken (t) =4sTimetaken(t)=4s
