A mass m is connected to the bottom of a verticalspring whose force constant is k. Attached to the bottomof the mass is a string that is connected to a second mass m, as shown in the figure. Both masses are undergoingsimple harmonic vertical motion of amplitude A. At theinstant when the acceleration of the masses is a maximum in theupward direction the string breaks, allowing the lower mass to dropto the floor. Find the resulting amplitude of motion of there maining mass. Express your answer in terms of the variablesA, m, k and appropriate constants.
A -42 nC charge is distributed uniformly along the x-axis from x = -1.1 m to x = 2 m . Consider a point at y = 2.2 m on the y-axis. find the total magnitude of the electric field at the point
The simple harmonic oscillator can be used as a model for the vibration of a diatomic molecule. Mass and Force Constant are on the order of 10^?26 kg and 10^3 N/m. This model will work if the temperature is sufficiently low (we assume it is in the gr..
