Particals along a straight line

[Confused_07]

Homework Statement

Starting from rest, a particle confined to move along a straight line is accelerated at a rate of 5 m/s^2.

Homework Equations

Does this mean that each second the particle's speed increases by 5m/s^2, or does it's speed stay at 5 m/s^2 and travels only 5 meters per second?

To help you answer your own question, I'll ask you a different one.

What is the definition of acceleration? If you know this, then you should be able to pick the right choice of the question you posed.
