Yes, assuming that the ball is thrown straight upwards and the y axis has been chosen to point straight up.

And now that you have the easy yes/no answer that you were looking for....

You could have chosen the x axis to point straight up, in which case vx would be 1 and vy would be zero.

Or you could have chosen both axes sloping in opposite directions at a 45-degree angle to the ground. In this case both vx and vy would be equal to √2/2 and there's nothing wrong with that choice except that it complicates the math for no good reason.

 if i choose x axis to point straight up, does that mean ay= 0 and ax= -9.8m/s^2?
