A block having mass m and charge +Q is connected to an insulating spring having a force constant k.
A block having mass m and charge +Q is connected to an insulating spring having a force constant k. The block lies on a frictionless, insulating, horizontal track, and the system is immersed In a uniform electric field of magnitude E directed as shown in the figure below. The block Is released from rest when the spring Is unstretched (at x = 0). We wish to show that the ensuing motion of the block is simple harmonic. (a) Consider the system...

A vertical elastic cord is stretched 0.306 m when a mass 1.66 kg is attached to it. The cord is then stretched an additional 0.114 m and released from rest. Assuming the cord is an ideal linear spring, how long does it take for the mass to reach its original equilibrium position? HINTS: First find the elastic constant of the elastic cord, using the fact that the gravitational weight mg of the mass is balanced by the upward pull of...
