A puck is moving on an air hockey table. Relative to an xy coordinate system at time thex components of the puck's initial velocity and acceleration are v_{0x} = 9.6m / s and a_{x} = 4.1m / (s ^ 2) The y components of the puck's initial velocity and acceleration are v_{0y} = 8.5m / s and a_{v} = - 2.8m / (s ^ 2) Find (a) the magnitude and (b) the direction of the puck's velocity at a time of t = 0.5s Specify the direction relative to the +axis
