A puck is moving on an air hockey table. Relative to an x, y coordinate system at time t = 0 s, the x components of the puck's initial velocity and acceleration are v0x = +5.6 m/s and ax = +6.3 m/s2. The y components of the puck's initial velocity and acceleration are v0y = +9.8 m/s and ay = -3.6 m/s2. Find (a) the magnitude v and (b) the direction θ of the puck's velocity at a time of t = 0.50 s. Specify the direction relative to the +x axis.

2. Relevant equations

v= u +at

v^2 = U^2 + 2as

s = ut +1/2at^2

s = vt +1/2at^2

3. The attempt at a solution

i dont know how to approach this, in fact i dont even know if im using the right equations. since there are X and Y component. it would be incorrect for me to find V by only using X or V ... please help.
