12-171. At the instant shown, the man is twirling a hose over his head with an angular velocity 0 = 2 rad/s and an angular acceleration 6 =3 rad/s². If

it is assumed that the hose lies in a horizontal plane, and water is flowing through it at a constant rate of 3 m/s, determine the magnitudes of the velocity and acceleration of a water particle as it exits the open end, r=1.5 m.
