Question

15 formula 1 point
what is the total mechanical energy of an object that has 224.3 j of potential energy and 104.8 j of kinetic energy?
report your answer to 1 decimal place. your permitted error is ±0.1 j. if your answer is negative, please make sure to include the negative sign.
answer

Explanation:

Step1: Recall the formula for total mechanical energy

The total mechanical energy \(E\) is the sum of potential energy \(U\) and kinetic energy \(K\), i.e., \(E = U+K\).

Step2: Substitute the given values

Given \(U = 224.3\space J\) and \(K=104.8\space J\). Then \(E=224.3 + 104.8\).

Step3: Perform the addition

\(224.3+104.8 = 329.1\)

Answer:

\(329.1\)
