What is the Velocity Vector of an Object After Undergoing Acceleration?

[warnexus]

Homework Statement

An object is moving in the x direction at 1.3 m/s when it undergoes an acceleration. Acceleration vector equals .52 j hat meter per second every second. Find its velocity vector after 4.4 seconds.
I am told to find x and y component of the velocity vector.

Homework Equations

Velocity vector x component equals initial velocity x component + acceleration vector x component times time.
Same applies for y component

The Attempt at a Solution

Use the above equation to find x component.
Since the object has a initial velocity in the x direction. Plug that into the equation. There is no acceleration in the x direction based on the problem. So acceleration vector x component is zero which makes initial velocity vector x same as final velocity x component. The final velocity x component is 1.3 m/s.

To find velocity y component insert. 52 j hat as it was a given. Insert time as well. Initial velocity y component was not given. So it is zero. The final velocity y component is 2.3 m/s.

Yeah, seems ok to me.
