Question

the object at point a has a potential energy of 360 j and a kinetic energy of 0 j. what is the total energy?
height (m) vs. time (s)
360 j
0 j
720 j

Explanation:

Step1: Recall total energy formula

Total energy ($E_{total}$) is the sum of potential energy ($E_{p}$) and kinetic energy ($E_{k}$), so $E_{total}=E_{p} + E_{k}$.

Step2: Substitute given values

Given $E_{p}=360\ J$ and $E_{k}=0\ J$, substitute into the formula: $E_{total}=360\ J + 0\ J$.

Step3: Calculate the result

$360\ J + 0\ J = 360\ J$.

Answer:

360 J
