# Easy shameful force and speed question

I haven't taken Physics in a long time, so my knowledge in Physics has pretty much faded away.
My question is, say I apply a force of 10 N to a block that has a mass of 2 kg and I want to find the velocity of the block when it's been pushed (or right after it's been pushed). How would I come about finding the speed?
I know the acceleration is 5, but all of the formulas I've looked at involved change in distance and time, and I don't know any of those.
Thanks.

Consider the definition of acceleration: the change in velocity per unit time. The speed of the block depends on how fast it was going initially and on how long you apply the force.

Oh.. it's how long I applied the force to the block? So, if I apply the force for 5 seconds the time in "a = delta v/ delta t" would be 5? Thank you.

That's right.
