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

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. the athlete is able to rotate the ball at the rate of 8.13 rev/s when the length of the chain is 0.600 m. when he increases the length to 0.900 m, he is able to rotate the ball only 6.04 rev/s. (a) which rate of rotation gives the greater speed for the ball? 6.04 rev/s 8.13 rev/s (b) what is the centripetal acceleration of the ball at 8.13 rev/s? m/s2 (c) what is the centripetal acceleration at 6.04 rev/s? m/s2
