Question

the object has a potential energy of 150 j and a kinetic energy of 0 j. what is the total energy of the object?
height (m) vs. time (s)
chart: height (m) on y - axis (0 - 10), time (s) on x - axis (0 - 4), blue line with peaks, red dot a at ~(3, 2.5)
options: 150 j, 300 j, 0 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 $E_{p} = 150$ J and $E_{k} = 0$ J, substitute into the formula: $E_{total} = 150 + 0$.

Step3: Calculate the result

$150 + 0 = 150$ J.

Answer:

150 J
