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 Vox = +4.3 m/s and ax = +1.5 m/s2. The y components of the puck's initial velocity and acceleration are Voy = +8.5 m/s and ay = -8.1 m/s2. Find (a) the magnitude v and (b) the direction 0 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 the +x axis
