Travelling at 40m/s, right?
Which direction does the force act?

Its acceleration is 40 m/s^2 at t=1 and its moving to the right.

The OP says the 4 kg object is traveling at 40 m/s^2. Usually, the velocity of an object is given, not its acceleration. Is this how the problem was originally specified? 'Traveling' implies velocity, otherwise, one would say an object is accelerating at X m/s^2.

Yes, I meant accelerating, I apologize. I "made" this problem to see what I could do given the acceleration

In specifying a problem, you can't mix cause and affect like this. You can either state the acceleration (and ask for something which can be deduced from that, like position, velocity..) or you can specify forces and let the acceleration be deduced.
And you still haven't said which direction the 20N acts in.

Nevermind all, this is a stupid, poorly stated question. I apologize
