Here's the data.  We compute the components of vave using the components of the displacement and the time interval. The y component of the average velocity stays constant at 2 m/s while the x component decreases. We take the limit as the time interval goes to zero to get the instantantaneous velocity components at t=1.3 s. The x-component is  1.84 m/s (about) and the y-component is 2.0 m/s.

Repeating the analysis at t=1.5 s, we find vx = 2.30 m/s and no change in vy .  Thus the acceleration is in the x direction, with one component parallel to the velocity (the particle is speeding up) and one component perpendicular to the velocity (changing the direction.)
