A dog running in an open field has components of velocity vx = 2.6 m/s and vy = -1.8 m/s at time t1 = 10.7 s . For the time interval from t1 = 10.7 s to t2 = 21.6 s , the average acceleration of the dog has magnitude 0.45 m/s2 and direction 29.0o measured from the +x-axis toward the +y-axis.
At time t2 = 21.6 s , what is the y-component of the dog's velocity?
What is the magnitude of the dog's velocity?
What is the direction of the dog's velocity (measured from the +x-axis toward the +y-axis)?
