Question

a body initially moving with a velocity of 20 metre per second in increase speed to 50 metres per second in 15 seconds calculate its acceleration ​

Answer 1

Answer:

Acceleration = 2

Explanation:

As we know that Acceleration is defined as,

                        "Rate of change of velocity"

Formula:

               ΔV/Δt

Given Data:

initial velocity= 20metre per second

final velocity  =50 metres per second

To Find:

Acceleration = ?

Calculation:

       Acceleration = Vf - Vi / Δt

                               =  50-20 / 15

                               = 30/15

        Acceleration = 2
