Answer 2

Constant velocity means zero acceleration. This in turn means zero force on the body. So once a force is applied to a body for short time, and the force is then removed, the body will continue to move with uniform velocity till such time that a force is again applied to it.

When the acceleration of the body is zero the velocity remain constant.

$= > v = u + at$

Where,

$v = final \: velocity$

$u = initial \: velocity$

$a = acceleration$

$t = time$

$= > when \: a = 0 \\ \: then\: v = u$
