A dog running in an open field has components of velocity v_x = 3.0 m/s and v_y = -1.2 m/s at time t_1 = 11.4 s. For the time interval from t_1 = 11.4 s to t_2 = 24.7 s, the average acceleration of the dog has magnitude 0.40 m/s^2 and direction 36.0 degree measured from the + x-axis toward the + y-axis .

a. At time t_2 = 24.7 s, 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)?
