Answer 1

Here are the answers to your questions based on the provided options:

**Question 1 A) Which is the equation for an object’s potential energy?**
- **Correct Response:** PE = mgh

**Question 2 A) In a baseball game, Joseph hits a ball to the outfield. When does the ball have the most potential energy?**
- **Correct Response:** when the ball reaches its highest point

**Question 3 A) The roof of an apartment building is 58 meters high. A water tank on the roof has a mass of 38,000 kilograms. What is the potential energy of the water tank?**
- To calculate potential energy (PE), use the formula:
\[ PE = mgh \]
Using \( m = 38,000 \, \text{kg} \), \( g = 9.81 \, \text{m/s}^2 \) (acceleration due to gravity), and \( h = 58 \, \text{m} \):

\[ PE = 38,000 \, \text{kg} \times 9.81 \, \text{m/s}^2 \times 58 \, \text{m} = 21,599,160 \, \text{J} \]

- **Correct Response:** 21,599,200 J (rounded slightly)

**Question 4 A) Which statement best describes an object’s potential energy?**
- **Correct Response:** The object’s mass, gravity, and height determine its potential energy.

**Question 5 A) Which scenario shows how to use collaborative learning to explore potential energy?**
- **Correct Response:** Members of a team work together to create a plan, and then members choose different tasks to carry out the plan.
