An experimental analysis of the natural oscillations in a particular structure shows the dominant frequencies of interest appear at below 200 Hz. However, frequency information also exists at 350, 450, and 750 Hz. If the signal is sampled at 400 Hz, how will the information in the aliased frequencies appear in the sampled data

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
