Meriam, Kraige & Bolton — Kinematics of Particles: Problem 2_115

2/115 The nozzle shown rotates with constant angular speed \(\Omega\) about a fixed horizontal axis through point \(O\). Because of the change in diameter by a factor of 2, the water speed relative to the nozzle at \(A\) is \(v\), while that at \(B\) is \(4v\). The water speeds at both \(A\) and \(B\) are constant. Determine the velocity and acceleration of a water particle as it passes (a) point \(A\) and (b) point \(B\).
