Finding velocity equation for object moving in 2 dimensions

AI Thread Summary
A 4 kg object is discussed, initially stated to be traveling at 40 m/s^2, which is corrected to indicate it is accelerating at that rate. The confusion arises from mixing terms of velocity and acceleration in the problem's specification. Participants emphasize the importance of clearly defining whether to state acceleration or forces to deduce other parameters. The direction of the 20N force acting on the object remains unspecified, leading to frustration among contributors. Overall, the discussion highlights the need for clarity in physics problem formulation.

Travelling at 40m/s, right?
along the x-axis at t=1 is influenced by a constant force of 20N.
Which direction does the force act?

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
