1. **State the problem:** We need to find the potential energy (PE) of an object with mass $1.0$ kg at point A, where the height is approximately $6$ m. 2. **Formula for potential energy:** $$PE = mgh$$ where $m$ is mass, $g$ is acceleration due to gravity, and $h$ is height. 3. **Given values:** - Mass $m = 1.0$ kg - Gravity $g = 10.00$ m/s² - Height at point A $h = 6$ m 4. **Calculate potential energy:** $$PE = 1.0 \times 10.00 \times 6 = 60$$ 5. **Interpretation:** The potential energy at point A is $60$ joules. This matches the graph label near point A, confirming our calculation.
