Another example would be a person pushing against a wall (action force), and the wall exerts an equal and opposite force against the person.
Answer:
437500Joules
Explanation:
Kinetic energy=1/2mvsquare
1/2 x 1400 x 25 x25
kinetic energy= 437500Joules
<span>Notice for the Carbon question they were the same element and the shared the same number of protons. so i think d. is the answer</span>
