Problem 2: A velocity field has been measured and its vector can be expressed as v = 3ti + xyj + ty²k, where x, y, z are coordinates in a Eulerian reference and t is time. (1) Determine the acceleration as a function of x, y, z, t. (2) What is the acceleration at a location x = 3 m, y = 1.5 m, z = 0 m, and time t = 5 s?
