Q. A sound source emits sounds of frequency 210 Hz that travel through still air at 340 m/s. The listener moves at 75 m/s relative to still air toward the stationary source. What is the wavelength of the sound between the source and the listener?

Q. A wrecking ball (weight = 5200 N) is supported by a boom, which may be assumed to be uniform and has a weight of 3400 N. As the drawing shows, a support cable runs from the top of the boom to the tractor. The angle between the support cable and the horizontal is 32°, and the angle between the boom and the horizontal is 48°.

(a) Find the tension in the support cable.

(b) Find the magnitude of the force exerted on the lower end of the boom by the hinge at point P.
