Question

kahan increases its speed from 20 kilometre per hour to30 kilometre per hour in 10 seconds its acceleration is​

Answer 1

Acceleration = Change in velocity / time taken

ACCELERATION = (V - U)/ T

Then

Initial velocity level = 20 KM/HR

Final velocity level= 30 KM/ HR

ACCELERATION = (30 - 20) KM/HR

= 30 KM/HR SQUARE = 2.777 m/s

Time = 10 seconds

Acceleration = 2.77 m/10s*s

Acceleration = 0.28 m/s^2

Here is the solutions."
