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 = +0.8 m/s and ax = +0.9 m/s2. The y components of the puck's initial velocity and acceleration are v0y = +1.6 m/s and ay = -2.4 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.
