Question

A racing car has a uniform acceleration on has 4 metre per second then what distance will it cover in 10 second find
​

Answer 1

$\Huge {\orange {\bf {\underline {\underline {AnSwer}}}:-}}$

• a = 4 m/s²
• t = 10 s
• u = 0 m/s

Find the velocity after 10 sec.

⇒ v = u + at

⇒ v = 0 m/s + 4 m/s² × 10 s

⇒ v = 40 m/s

Using relation → v² - u² = 2as

a = 4 m/s²

u = 0 m/s

v = 40 m/s

⇒ (40)² - (0)² = 2(4)(s)

⇒ 1600 - 0 = 8s

⇒ 1600 = 8s

⇒ s = 1600/8

⇒ 200 m

Therefore, the distance covered is 200 m.

Answer 2

Answer:

Question:-

»»» A racing car has a uniform acceleration on has 4 metre per second then what distance will it cover in 10 second find

Given:-

A racing car uniform acceleration of 4m/s²

then distance covered in 10sec

a = 4m/s² ; t = 10sec ; s = ? ; u = 0

To Find:-

s = ? ; v =?

Answer:-

v = 40 m/s ; s = 200

Solution:-

»»»v = u + at

v = 0 + 40

v = 40m/s

now, a = 4m/s² ; t = 10 sec ; u = 0 ; v = 40 ; s = ?

s = ut + 1/2 at²

s = 0 × 10 + 1/2 × 4 × 10²

s = 2 × 100

s = 200 m

hope this helps you
