Question

A body is moving with an uniform velocity of 40 m/s , find its acceleration after 10 second

Answer 1

In uniform velocity,acceleration always ZERO...☺

Answer 2

Answer:

The acceleration after 10 second is Zero.

Explanation:

               We know acceleration is velocity per unit of time since the velocity here is uniform that is the body is moving with the constant velocity of 40 meter per second.

                Hence there is no change in velocity E with time hence the acceleration fear can be considered 0.

Let us prove it with the help of Newton's Law of Motion:

V= u + at

V=u= 40m/s (since body is moving with constant velocity)

Hence at = 0  

$=\mathrm{a} \times 10=0$

Therefore, a=0

Acceleration becomes zero.
