Problem 1- A dog running in an open field has components of velocity vx = 2.2m/s and vy = -2.5m/s at time t1 = 12 s. For the time interval from t1 = 12 s to t2 = 24 s , the average acceleration of the dog has magnitude 0.55 m/s2 and direction 25.5∘ measured from the +x−axis counterclockwise. At t2 = 24 s What is the speed of the dog and what is the direction of its motion?
