Question

A car attains a velocity of 72km/h in 10sec starting from rest . calculate the average velocity .. please answer​

Answer 1

Answer: Average velocity = 2m/s

Explanation: displacement = 72km/h = 72 ×5/18 =20m/s

Time = 10sec

Average velocity =displacement / time

=20/10

= 2m/s

Answer 2

Explanation:

as we can convert km/h into m/s by multiplying it by 5/18
