An object of mass m attached to a spring of force constant k oscillates with simple harmonic motion. The maximum displacement from equilibrium is A and the total mechanical energy of the system is E.
What is the object's velocity when its potential energy is 2/3 E ?
A) +or- the square root of k\m x A
B) +or- the square root of k\m x square root of 2/3 x A
C) +or- the square root of k\m x A/square root of 3
D) +or- the square root of k\m x A/square root of 6
