• In the given question information given about a body starts to move from rest and travels with a uniform acceleration of 7m/s .

• We have to find distance travelled bg body in 4 second.

$\green{\underline\bold{Given :}} \\ :\implies \text{Initial\:velocity(u)=0\:m/s} \\ \\ :\implies \text{Acceleration(a)= 7\:m/s}^{2}\\ \\ :\implies \text{Time(t)= 4\:sec}\\ \\ \red{\underline \bold{To \: Find : }} \\ :\implies \text{Distance(s)=?}$

• According to given question :

$\bold{Using \: second \: equation \: of \: motion } \\ : \implies s = ut + \frac{1}{2} {at}^{2} \\ \\ : \implies s = 0 \times 4 + \frac{1}{2} \times 7 \times {4}^{2} \\ \\ : \implies s = \frac{1}{2} \times 7 \times 16\\ \\ : \implies s =7 \times 8 \\ \\ \green{ : \implies \text{s =56\: m}}$
