A dog running in an open field has components of velocity Vx = 2.6 m/s and Vy = -1.8 m/s at time t = 10 sec. The dog is running with constant acceleration of 0.45 m/s2 and direction 31.0º measured from +x-axis. At 20 sec, (a) what are the x- and y-components of dog’s velocity? (b) What are the magnitude and direction of dog’s velocity?
