the start?
a) 100 m
b) 200 m
c) 300 m
d) 400 m
of moving to

Answer 1

★$\color{darkblue}\underline{\underline{\sf Given-}}$

• Acceleration of racing car (a) = 8m/s²
• Time (t) = 10s

★$\color{darkblue}\underline{\underline{\sf To \: Find-}}$

• Distance covered in 10 sec (s)

★$\color{darkblue}\underline{\underline{\sf Formula \: Used -}}$

$\color{violer}\bullet\underline{\boxed{\sf s=ut+\dfrac{1}{2}at^2}}$

$\implies{\sf s=0+\dfrac{1}{2}×8×(10)^2 }$

$\color{red}\implies{\sf s=400m}$

★$\color{darkblue}\underline{\underline{\sf Answer-}}$

Option (d) 400m

Distance covered in 10 sec is $\color{red}{\sf 400m}$
