Question

a racing car has a uniform acceleration of 8 m s? what distance will it cover in 10 second after start.​

Answer 1

Answer:

400m

Explanation:

From Newton's laws of motion,

s = ut + 1/2 at²

Here u = 0

s = 1/2 at²

= 1/2 × 8 × (10)²

= 400m

Answer 2

Explanation:

${\bold{\sf{→ \: \: \: \: \: \: \: \: \: \: \: \: \: \: speed = 8m/s}}}$

${\bold{\sf{→ \: \: \: \: \: \: \: \: \: \: \: \: \: time = 10 seconds}}}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: {\small{\sf{\red{We \: know \: that \: Speed \: = \: \frac{Distance}{Time}}}}}</p><p></p><p></p><p>$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: {\bold{\sf{→ 8m/s = \frac{Distance}{10}}}}$

${\bold{\sf{→ \: \: \: \: \: \: \: \: \: \: \: \: \: \: Distance = 8 × 10 }}}$

${\bold{\sf{→ \: \: \: \: \: \: \: \: \: \: \: \: \: \: Distance = 80 m}}}$
