Chapter 3, Problem 16P

A puck is moving on an air hockey table. Relative to an x, y coordinate system at time $t=0 \text{s},$ the $x$ components of the puck’s initial velocity and acceleration are $v_{\text{o}x}=+1.0 \text{m}/\text{s}$ and $a_x=+2.0 \text{m}/{\text{s}}^2.$ The $y$ components of the puck's initial velocity and acceleration are $v_{\text{oy}}=+2.0 \text{m}/\text{s}$ and $a_y=-2.0 \text{m}/{\text{s}}^2.$ Find the magnitude and direction of the puck's velocity at a time of $t=0.50 \text{s}.$ Specify the direction relative to the $+x$ axis.
