How do I prove that total mechanical energy is constant for a spring executing simple harmonic motion by INTERGRATION of a=-(w^2) (x (t))?

Mass of electrom = m charge on electron = e velocity of electron = v Volts = joules/coulomb kinetic energy of electron = e * V joules = ½mv² v² = 2V * e/m Taking e/m = 1.759 * 10^11 C/kg v =?(2Ve/m) =?(200 * 1.759 * 10^11) v = 5.93 * 10^6 m/s.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
