Compute all parts of give question:

Question: A dog running in an open field has components of velocity vx = 3.5m/s and vy = -1.4m/s at time t1= 10.7s. For the time interval from t1 = 10.7s to t2= 19.1s, the average acceleration of the dog has magnitude 0.36m/s2 and direction 29.0 degree measured from the +x axis toward the +y axis.

Part A: At time t2 = 19.1s, what are the x-component of the dog's velocity?

Part B: At time t2 = 19.1s, what are the y-component of the dog's velocity?

Part C: What is the magnitude of the dog's velocity?

Part D: What is the direction of the dog's velocity (measured from the +x?axis toward the +y axis)?

I need help to determine the magnitude of the dog's velocity.
