Two musicians are comparing their trombones. the first produces a tone that is known to be 438 hz. when the two trombones play together they produce 6 beats every 2 seconds. which statement is true about the second trombone?
it is producing a 444-hz sound, and could be producing no other sound frequency.
it is producing either a 436-hz sound or a 440-hz sound.
it is producing either a 435-hz sound or a 441-hz sound.
it is producing either a 432-hz sound or a 444-hz sound.
it is producing a 441-hz sound, and could be producing no other sound frequency.

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.

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
