Question

a body is moving with a velocity of 10m/s. if the motion is uniform, what willbe the velocity after 10s ?and why?

Answer 1

It will be 10 m/s.
as the motion is uniform so velocity will also be uniform. And so after 10 second it will be
10 m/s.

Answer 2

The velocity of the body is 10 m/s.

The motion is uniform which means that there is no acceleration involved or there is no change in the magnitude of the velocity of motion with respect to time.

So, as time will change there will be no change in velocity of the body at all. The velocity of the body will remain the same as 10 m/s .

So, after any time (also 10 s) the velocity will be the same as 10 m/s.

Also, we know that v = u + a t

and a = 0 m/s^2_______as velocity is uniform

t = 10 s , u = 10 m/s

so, v = u + 0×10

so, v = 10 m/s
