A horizontal flow of water is described by the velocity field V= (-Ax+Bt)i+(Ay+Bt)j, where A=1/s and B=2m/s2, x and y are in meters, and t is in seconds. Find expressions for the local acceleration, the convective acceleration, ans the total acceleration. Evaluate these at point (1,2) at t=5s. Evaluate deltap at the same point and time.
