Question

At mass-spring constant which statement is NOT true?

A). It is an example of simple harmonic motion
B). At equilibrium position the speed is maximum
C). At equilibrium position, the speed is zero
D). At equilibrium position, the force equals zero

Answer 1

Explanation:

Answer D is the only false statement. At the equilibrium position, x=0, the elastic potential energy of the system (PEs=21kx2) is a minimum and the kinetic energy is a maximum.
