[20] A helicopter flying with a horizontal velocity vo has its rotor axis tilted by an angle y from the vertical as shown, prepares for a vertical ascent by decreasing y at a constant rate w rad/s. At the same time, the velocity of 0 is decreasing at the rate ao. Write the expressions for the velocity and acceleration of point B on the tip of the blade as it crosses the x-axis in the position shown. The x - and z - axes are fixed to the helicopter body in the vertical plane, and the z-axis coincides with the rotor axis. The constant angular speed of the rotor is p, clockwise as viewed from above.
