Answer:

Step-by-step explanation:





The kinetic energy is calculated through the equation,
KE = mc²
where KE is kinetic energy, m is mass, and c is the masses. Substituting the known values,
KE = (5 kg)(3 x 10^8)²
KE = 4.5 x 10^17 J
To learn multiplication you have to practice them time after time. They are really helpful in older grades.
- Play multiplication games
- Do quizzes
- Ask yourself questions
