When is the magnitude of the acceleration of a mass on a spring at its maximum value?
when the mass has a speed of zero
when the mass is moving upward
when the mass has no displacement
when the mass is 1/2x

What is the rate of change in a objects position?

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
