Question

A car travelling at 40 kilometre per hour speed up to 80 km per hour in 5 seconds what is its acceleration.

Answer 1

HELLO FRIEND HERE IS YOUR ANSWER :-

initial speed , u = 40 km/h

= 11.11m/s

final speed, v = 80km/h

= 22.22m/s

time , t = 5s

We know that, v = u + at

a = (v - u)/t

a= (22.22 - 11.11)/5

a= 2.22m/s²

HOPE IT HELPS YOU ☺️☺️
