Explanation

Formula to be used,

  • 1st equation of motion, v = u + at
  • • 3rd equation of motion,v² - u² = 2 as

Solution,

Putting all the values, we get

v=u + at

⇒0 = u + (-0.5) × 20

⇒-u=-0.5 × 20

⇒u = 10 m/s

Hence, the initial velòcity of the car is 10

city of the car is 10m/s.

Now, the distance covered,

v²-u² = = 2as

⇒ (0)²-(10)² = 2 × (-0.5) × s

⇒-100 = - 1s

⇒ s = 100 m

Hence, the distance covered is 100 m.
