Question

A racing car has a uniform acceleration of 4m/s square the distance covered by the car in 10 seconds after the start

Answer 1

s = ut + 1/2 at²

s= 0+ 1/2 ×4 ×100 (since u= 0 )

s= 200

thus the car covers 200 m

hope it helps

pls pls pls pls pls follow me

Answer 2

$\huge\star\:\:{\orange{\underline{\purple{\mathcal{Solution}}}}}$

➝ Acceleration = $\:\sf{4\: \dfrac{m}{s}^{2}}\:$

➝ Initial velocity = $\:\sf{0\: \dfrac{m}{s}}\:$

➝Time = $\:\sf{10s}\:$

$\huge{\orange{\underline{\red{\mathscr{We\: know}}}}}$ :-

$\boxed {s \: = \: ut \: + \: \dfrac{1}{2}{at}^{2}}$

$⟹$ $s$ $=$ $0$ $×$ $10$ $+$ $\dfrac{1}{2}$ $×$ $4$ $×$ ${10m}^{2}$

$\text{⟹\:\:s\:\:=\:\:2\:\:×\:\:100m}$

$\text{⟹\:\:s\:\:=\:\:200m}$

Thus racing car will cover a distance of 200m after start in 10s with given acceleration.
