Answer 2

$\blue{\bold{\underline{\underline{Answer:}}}}$

$\green{\tt{\therefore{Distance\:travel=800\:m}}}$

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

$\green{\underline \bold{Given :}} \\ \tt: \implies Acceleration(a) = 4 \: m/ {s}^{2} \\ \\ \tt: \implies Time(t) =20\: m \\ \\ \red{\underline \bold{To \: Find :}} \\ \tt: \implies Distance(s)= ?$

• According to given question :

$\tt \circ \: Initial \: velocity = 0 \: m/s\\ \\ \bold{As \: we \: know \: that} \\ \tt: \implies s = ut+\frac{1}{2}at^{2}\\ \\ \tt: \implies a=0\times 20+ \frac{1}{2} \times 4 \times 20^{2} \\ \\ \tt: \implies s= 2\times 400 \\ \\ \green{\tt: \implies s = 800\:m} \\ \\ \blue{\bold{Some \: related \: formula : }} \\ \orange{ \tt \circ \: v = u + at} \\ \\ \orange{ \tt \circ \: {v}^{2} = {u}^{2} + 2as}$
