3) (25 points) A fluid has velocity components of u=x(t+2y)[m/s] and v=2x2[m/s], where x and y are in meters and t is in second. a) (5 points) Please determine the magnitude of the velocity of a particle passing through the point (1 m,1m) when t=2s. b) ( 10 points) Please determine the acceleration when a particle passing through the point ( 1m,1m) at t=2s. c) (10 points) Please determine the streamline of a particle passing through the point ( 1m,1m) when t=2s
