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 5.0 cm.
Cuando el auto, con la persona a bordo, cae en un hoyo, comienza a oscilar verticalmente en
un movimiento armónico 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. (10 puntos)

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.

Arunner is training for an upcoming marathon by running around a 100-m-diameter circular track at constant speed. let a coordinate system have its origin at the center of the circle with the x-axis pointing east and the y-axis north. the runner starts at (x, y) = (50 m, 0 m) and runs 2.5 times around the track in a clockwise direction.

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?
