energy is the ability to do work while work is the dot product of force and displacement
Answer:
a) 
b) 
c) 
Explanation:
a) In the equilibrium position of the system, that is when the spring is not elongated, the potential energy is zero. Therefore, the total energy of the system is the maximum kinetic energy:

b) The force constant of the spring can be calculated from the natural frequency of the system:

Recall that
, that is the distance traveled in one revolution divided into the time of one revolution. Replacing and solving for k:

c) The maximum speed is directly proportional to the amplitude of the motion:

<span>because in any atom the electrons are in the outer orbitals while protons are within the nucleus together with the neutrons. If energy is supplied electrons can jump to higher energy levels and leave the lower orbitals.
Especially in metals the conduction band is partially filled at room temperature with allows free flow of electrons throughout the metal thus they carry charge.
(it requires huge amounts of energy to remove a proton from the nucleus such things happen on the surface of sun).</span><span>
