Two eagles fly directly toward one another, the first
at 15.0 m/s and the second at 28.0 m/s. Both screech, the
first one emitting a frequency of 2700 Hz and the
second one emitting a frequency of 3800 Hz. What
frequencies (in Hz) do they receive if the speed of sound
is 330 m/s?

17 points) One simple pendulum and the physical pendulums (disk and rod) are suspended on the crossbar, as shown in figure. (a) Calculate the natural linear frequency of the simple pendulum, if the length of the simple pendulum is -1.6 m (b) Calculate the natural angular frequency of the disk. The radius of the disk is R-0.5 m; moment of inertia about an axis through the center of mass is ICM = mR2 - (c) Calculate the natural period of...
Two trains on separate tracks move toward one another. Train 1 has a speed of 110 km/h, train 2 a speed of 85.0 km/h. Train 2 blows its horn, emitting a frequency of 500 Hz. What is the frequency heard by the engineer on train 1? (Assume the speed of sound is 345 m/s.)
