$\green{\therefore{\text{Acceleration}\approx17.14\:m/s^{2}}}$

$\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

• In the given question information given about a body starts from rest and moves with uniform acceleration its velocity on 8th second is120m/s.

• We have to find the acceleration.

$\green{\underline\bold{Given :}} \\ :\implies \text{Initial\:velocity(u)=0\:m/s} \\ \\ :\implies \text{Final\:velocity(v)= 120 \:m/s}\\ \\ :\implies \text{Time(n)= 8th\:sec}\\ \\ \red{\underline \bold{To \: Find : }} \\ :\implies \text{Accleration(a)= ?}$

• According to given question :

$\bold{Using \: formula \: velocity\:at\:the\:begining\:of\:nth\:sec } \\ : \implies v = u + a(n-1) \\ \\ : \implies 120= 0+a(8-1) \\ \\ : \implies a=\frac{120}{7} \\ \\ \green{ : \implies a\approx17.14m/s^{2}}$
