Question

A velocity of a car increases from 36 km/h to 180 km/h in 10s.Its acceleration is:

Answer 1

Answer:

14.4m/s^2

MARK as BRAINLIEST please

Answer 2

Answer:

4 m / sec²

Explanation:

Given :

Initial velocity u = 36 km / hr

= > u = 36 × 5 / 18 m / sec

= > u = 10 m / sec

Final velocity v = 180 km / hr

= > v = 180 × 5 / 18 m / sec

= > v = 50 m / sec

Time t = 10 sec

We know :

a = Δ v / Δ t

= > a = ( v - u ) / t

= > a = ( 50 - 10 ) / 10

= > a = 40 / 10

= > a = 4 m / sec²

Therefore , acceleration of car is 4 m / sec²
