Newtons. Force is mass times acceleration. Mass is measured in kilograms (kg) and acceleration is measured in meters per second squared (m/s^2.) These units (kg and m/s^2) multiplied together like in the equation force equals mass times acceleration (F=ma) gives a product with Newtons as the unit.

Image is missing so I have attached it.

Also, the options are missing and it is;

A) KE is has a maximum value at position 3. EPE has a maximum value at position 2. GPE has a maximum value at position 1.

B) KE is has a maximum value at position 1. EPE has a maximum value at position 2. GPE has a maximum value at position 3.

C) KE is has a maximum value at position 2. EPE has a maximum value at position 3. GPE has a maximum value at position 1.

D) KE is has a maximum value at position 1. EPE has a maximum value at position 3. GPE has a maximum value at position 2.

E) KE is has a maximum value at position 2. EPE has a maximum value at position 1. GPE has a maximum value at position 3.

Answer:

Option C is the correct answer which says; KE is has a maximum value at position 2. EPE has a maximum value at position 3. GPE has a maximum value at position 1.

Explanation:

If an object vibrates about its mean position, under the influence of a restoring force, such that restoring force is directly proportional to the displacement from the mean position, the motion of the object is called simple harmonic motion. During Simple harmonic motion, the sum of Kinetic and potential energy remains constant.

Now, Looking at the diagram, Kinetic Energy (KE) is maximum at position 2.

Looking at the options, only C and E agree with this.

Thus, our answer is either option C or E.

However, Option E is not going to be right because it says that GPE is at a maximum at position 3, which is not true as the maximum GPE will occur at position 1.

Thus,

Option C fulfills that and therefore will be the correct answer.
