​

Answer 1

$\sf\star{\underline\bold\red{{QUESTION:-}}}$

✓✓A racing car has a uniform acceleration of 4m/s².what distance will it covers in 10 sec.

$\sf\star{\underline\bold\purple{{GIVEN:-}}}$

• $\sf\: Acceleration\:(a)\:=4m/{s}^{2}$

• $\sf\: Initial\: velocity\:(u)\:=0m/s$

• $\sf\:time\:(t)\:=10\:s$

$\sf\star{\underline\bold\green{{To\:Find:-}}}$

$\sf\implies\: Distance\: covered\:(s)\:=?$

$\sf\star{\underline\bold\orange{{SOLUTION:-}}}$

$\sf\boxed\star\pink{\underline{\underline{{Using\: Second\: equation\:of\: motion:-}}}}$

$\sf\:s=ut+\dfrac{1}{2}a{t}^{2}$

$\sf\implies\:s=0\times\:10s+\dfrac{1}{2}\times\:4m/{s}^{2}\times\:{(10s)}^{2}$

$\sf\implies\:s=\dfrac{1}{2}\times\:4m/{s}^{2}\times\:100{s}^{2}$

$\sf\implies\:s=2\times\:100m$

$\sf\green{{\implies\:s=200m}}$

Answer 2

Answer:

200

Explanation:

S=UT+1/2at²

S=0×10+1/2×4m/s²×10²

S=200m
