a car moving on a staraight path covers a distance of 1 km due to east in 100s.what is i)speed ii)the velocity of the car

Answer»

AnsWer :

i) 10 m/s.

ii) The velocity of the toward the east at Speed of 10m/s.

Given :

  • A car moving on a STRAIGHT path.
  • Distance COVER 1 km.
  • time is 100 second.

Formula REQUIRED :

\tt D = S \times t.

  • D distance.
  • S Speed.
  • t time.

Solution :

  • 1 km = 1000 m.

i)

We have formula,

\tt \implies D = S  \times t.

\tt \implies 1000 = S\times 100

\tt \implies S =  \frac{1000}{100}

\tt \implies S = 10 \: m / s.

ii)

  • When Car moving toward east than, the velocity of car is 10 m/s toward east.
