Question

a body is moving with a velocity of 20 m per second if the motion is uniform what will be its velocity after 10 second

Answer 1

Answer:

Velocity remains the same as 20m/s

Explanation:

Given :

Initial velocity = 20 m/s

Final velocity =?

Time = 10 seconds

The Three Equations Of Motion are

v = u + at,

s = ut + 1/2 at^2

v^2 - u ^2 = 2as

here we may use the first equation of motion,

since it is a uniform motion there is no change in the velocity.

acceleration = 0

v = 20 + 0 X 10

v = 20 m/s
