A puck is moving on an air hockey table. Relative to an x, y coordinate system at time t = 0s, the x components of the puck's initial velocity and acceleration are vox = +4.0 m/s and ay = +5.2 m/s2. The y components of the puck's initial velocity and acceleration are Voy = +9.5 m/s and dy = -8.6 m/s2. Find (a) the magnitude vand (b) the direction @ of the puck's velocity at a time of t = 0.50 s. Specify the direction relative to the +x axis. (a) v= i (b) 0 = i degrees v the +x axis
