In summary, when trying to confirm if your answer is correct or not, it is important to review the steps you took to solve the problem and make sure you followed all instructions. If your answer is different from the expected answer, you should double check your calculations and seek help if needed. There are multiple methods you can use to confirm your answer, such as using a calculator or a different formula. Additionally, there are shortcuts you can use to check your answer without redoing the entire problem, such as plugging the answer back into the original equation or estimating the answer. However, if you are still unsure about your answer, it is best to seek help from a colleague or teacher to avoid submitting an incorrect answer.

i think your maximum kinetic energy should be 1/2*m*v^2 = 1/2*m*w^4*x^2 in stead of 1/2*m*w^2*x^2

Your solution is correct. The maximum kinetic energy of the mass can be expressed as:

Kmax = 1/2 * m * (2π * a * √(k/m))^2

or in simplified form as:

Kmax = π^2 * m * a^2 * k

Great job on solving this problem!
