A body is moving with a velocity of 15 m/s. If the motion is uniform, what will be the velocity. after 12 s?

When a body moves with uniform velocity it means that it covers equal distance in equal intervals of time. So the velocity after ten seconds will remain the same that is 15 meters per second.
hope it helped :)

Initial velocity = 15 m/s
Final velocity = ?
Time taken = 12 s
acceleration = 9.8 m/s (when it is not given)
Therefore by newton's first equation of motion
v = u + at
= 15 + 9.8 × 12
= 132.6
Answer : Final velocity will be 132.6 m/s
