En un estudio de los efectos de un accidente sobre los ocupantes simulados de los dos vehículos que se muestran en la figura, el automóvil A de 1900 lb con velocidad VA = 30 mi/h choca con el automóvil B de 2800 lb con velocidad VB = 20 mi/h. El coeficiente de restitución del impacto es e= 0.15 y la duración de la colisión es de 0.22 s. determine la magnitud de la aceleración promedio a la que están sometidos los ocupantes de cada uno de los automóviles

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s.part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.
