Question

A racing car has a uniform acceleration of 4 metre second - 2 what distance will it cover in 10 seconds

Answer 1

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

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

$\sf\star\bold\purple{{ANSWER:-}}$

$\sf\implies\:s=200\:m$

$\sf\star\bold\pink{{GIVEN:-}}$

• Acceleration (a) = 4m/s²

• Initial velocity (u) = 0m/s

• Time (t) = 10 s

• Distance covered (s) = ?

$\sf\star\bold\green{{SOLUTION:-}}$

$\sf\: Using\:Second\: equation\:of\:motion$

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

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

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

$\sf\implies\boxed{\boxed{\sf\therefore\:s=200m}}$

hence, racing car will cover a distance of 200m after start in 10 sec with given acceleration.
