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

Answer:

The distance covered is 200 m.

Given :

Uniform acceleration = 4 m/s²

Initial velocity = 0 m/s

Time = 10 sec

Solution :

• 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.
