A dog running in an open field has components of velocity vx= 2.8 m/s and vy= -2.3 m/s at time t1= 10.3s . For the time interval from t1= 10.3 to t2= 22.7 , the average acceleration of the dog has magnitude 0.43 m/s2 and direction 33.5 degree measured from the +x-axis toward the +y-axis .

A) At time t2= 22.7s , what are the x- and y-components of the dog's velocity?

B) What is the magnitude of the dog's velocity?

C) What is the direction of the dog's velocity (measured from the +x-axis toward the +y-axis?
