A fluid flow is defined by u = (0.4x2 + 2t) m/s and v = (0.8x +2y) m/s, where x and y are in meters and t is in seconds.
Part A
Determine the magnitude of the velocity of a particle passingthrough point x = 12.8 m, y = 1 m if it arrives when t = 3 s.
V=
Part B
Determine the direction of the velocity of a particle passingthrough point x = 12.8 m, y = 1 m if it arrives when t = 3 s. Enteryour answer as the angle ?V, which the velocity makes with the xaxis, measured counterclockwise from the positive x axis.
.
Part C
Determine the magnitude of the acceleration of a particlepassing through point x = 12.8 m, y = 1 m if it arrives when t = 3s.
Part D
Determine the direction of the acceleration of a particlepassing through point x = 12.8 m, y = 1 m if it arrives when t = 3s. Enter your answer as the angle ?a, which the acceleration makeswith the x axis, measured counterclockwise from the positive xaxis.
