A dog running in an open field has components of velocity vz = 2.0 m/s and vy = -1.8 m/s at time t = 10.0 s. For the time interval from t = 10.0 s to t2 = 21.0 s, the average acceleration of the dog has magnitude 0.50 m/s? and direction 31.0° measured from the +r-axis toward the +y-axis. Part A At time t2 = 21.0 s, what is the r-component of the dog's velocity? Express your answer with the appropriate units. ANSWER: Vz = Part B At time t2 = 21.0 s, what is the y-component of the dog's velocity? Express your answer with the appropriate units. ANSWER: Vy = Part C What is the magnitude of the dog's velocity? Express your answer with the appropriate units. ANSWER: |v| =
