If your friend said that kinetic energy was changing to potential energy at point c, how would you respond?

a) your friend is correct.

b) your friend is incorrect, at this point, the cannon ball just has kinetic energy.

c) your friend is incorrect, at this point, the cannon ball just has potential energy.

d) your friend is incorrect, at this point, the cannon ball is converting kinetic to potential energy.

C.  Your friend is incorrect, at this point, the cannon ball just has potential energy.

Explanation:

Potential energy is the kind of energy that an object has due to its position.

The unit for energy in the International System of Units (SI) is the joule, which has the symbol J.

Potential energy is usually related to forces that act on a body in a way that the total work done by these forces on the body depends only on the initial and final positions of the body in space.

These forces, receive the name of conservative forces and can be represented at every point in space by vectors expressed as gradients of a certain scalar function called potential.

explanation:

to eliminate ambiguous remote or broad reference it is necessary to focus on anaphoric reference. by definition "anaphoric reference means that a word in a text refers back to other ideas in the text for its meaning." the references should be clear and leave no room for ambiguity.

in the first case the pronoun it probably refers to the car but it has not been mentioned before so we should replace it for the car. in doing so the statement becomes clear.

in sentence number   two   the pronoun he refers to charles dickens the author. yet, the first half of the sentence is about the book a tale of two cities. to repair this it would be better to rephrase the first half : after i read   a tale of two cities by dickens, he so as to remove the remote reference.
