Answer 2

Answer:

when there is a non-zero net force, it will constantly changing the speed or velocity of the object.

As time goes on the velocity will be changing for ever. This process will continue as long as there is force.

It ceases only when the force is zero. And thereafter it will move with constant speed, the speed that it has attained at the instant of cessation of force.

Answer to your question is , therefore, it will certainly move with constant speed. ( sometimes the constant speed may also be zero).
