A puck is moving on an air hockey table. Relative to an x, y coordinate system at time t = 0s, thex components of the puck's initial velocity and acceleration are Vox = +9.1 m/s and ax = +7.6 m/s2. The y components of the puck's initial velocity and acceleration are Voy = +8.9 m/s and ay = -5.9 m/s2. Find (a) the magnitude v and (b) the direction 8 of the puck's velocity at a time of t = 0.50 s. Specify the direction relative to the +x axis. (a) v = (b) 0= i i degrees + the +x axis
