A2 kg mass attached to a massless spring undergoes undamped simple harmonic motion, with a position given by , where x is in m and t is in s. what is the total mechanical energy in the system?

Total mechanical energy in the system, E = 36 J

Explanation:

It is given that,

Mass of the object, m = 2 kg

It undergoes undamped simple harmonic motion, with a position given by :

The general equation of SMH is given by :

A is the amplitude of wave, A = 2 m

is the angular frequency

We know that the sum of kinetic and potential energy is equal to the mechanical or total energy of the system. The formula for the mechanical energy is given by :

So,

E = 36 joules

So, the total mechanical energy in the system is 36 joules. Hence, this is the required solution.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
