6 Los amortiguadores de un automóvil viejo con masa de 1800 kg están gastados. Cuando una persona de 780 N se sube lentamente al auto en su centro de gravedad, el auto baja 30 cm.
Cuando el auto, con la persona a bordo, cae en un hoyo, comienza a oscilar verticalmente en
um movimiento armonico simple. Considere el auto y la persona como un solo cuerpo (una sola
masa) en un solo resorte y calcule (a) el periodo y (b) la frecuencia de oscilación.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
