Question

the potential energy of the object at point a is 480 j and the total energy is 960 j. what is the kinetic energy?

Explanation:

Step1: Recall the energy conservation formula

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

Step2: Rearrange the formula to solve for \( KE\)

We can rewrite the formula as \( KE=E - PE\).

Step3: Substitute the given values

Given \( E = 960\space J\) and \( PE = 480\space J\), then \( KE=960 - 480\).

Step4: Calculate the result

\( KE = 480\space J\).

Answer:

\(480\space J\)
