The helicopter of Figure P1.9 has a horizontal speed of \(110 \mathrm{ft} / \mathrm{s}\) and a horizontal acceleration of \(3.1 \mathrm{ft} / \mathrm{s}^{2}\). The main blades rotate at a constant speed of \(135 \mathrm{rpm}\). At the instant shown, determine the velocity and acceleration of particle \(A\).
