Question

What is the acceleration required to change the velocity of an object from 20 m/s to 40 m/s across displacement of 40 m.

Answer 1

This should be the solution.

Answer 2

Hey Mate here is your answer.

Given:-

→u=20m/s →v=40m/s →s=40m

To find:- Acceleration(a)

Solution:-

→v²=u²+2as [3rd equation of motion]

→(40)²=(20)²+2×a×40m

→1600-400=80a

→1200÷80=a

→15m/s=a

Hope it helps.
