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 cannonball just has kinetic energy c) your friend is incorrect, at this point, the cannonball just have potential energy d) your friend is incorrect, at this point, the cannonball is converting kinetic to potential energy

funny of u to assume I have friends

If I remember anything from that part of my education (not great at physics) I'd say the answer is A, though I admit i'm not 100% sure

I dunno how to explain, once it hits that's the energy that was converting I guess.

the answer is C

Explanation:

When an object is at its highest point( in height) it just has potential energy, nothing else. When it falls back down then it’s converting back to kinetic energy.
