```							Initial velocity of car = 36 km/hr due north Final velocity of car = 36 km/hr due westmagnitude of change in velocity = sqrt(36^2 +36^2) = 36root(2)(since velocity is a vector, so direction has to be taken into account)Acceleration = change in velocity/time = 2.929 m/s^2 (5/18 converts km/hr to m/s)
