Question
**Problem 8.46** An object moves along the x-axis, subject to the potential energy shown in the figure (Figure 1). The object has a mass of 1.1 kg and starts at rest at point A. **Part C** What is the object's speed at point D? Express your answer using two significant figures. \[v_D = \quad \text{m/s}\] [Submit] [Request Answer] **Part D** What are the turning points for this object? Check all that apply. - [ ] Point A - [ ] Point B - [ ] Point C - [ ] Point D - [ ] Point E **Figure Description:** The graph displays the potential energy \( U \) on the y-axis versus the position \( x \) on the x-axis. Key points are marked from A to E across the curve. 1. **Point A**: \( x \approx 0.5 \, \text{m} \) with a potential energy of about 10.0 units. 2. **Point B**: \( x \approx 1.8 \, \text{m} \) with potential energy near 2.0 units (local minimum). 3. **Point C**: \( x \approx 3.0 \, \text{m} \) with potential energy around 5.0 units (local maximum). 4. **Point D**: \( x \approx 4.0 \, \text{m} \) with potential energy near 3.0 units (local minimum). 5. **Point E**: \( x \approx 5.2 \, \text{m} \) with increasing potential energy past 10.0 units. The curve indicates potential energy valleys and peaks, identifying potential turning points or points of equilibrium. Points of interest may signify where kinetic energy changes or motion may reverse.

## Problem 8.46 An object moves along the x-axis, subject to the potential energy shown in the figure. The object has a mass of 1.1 kg and starts at rest at point A. ### Part A What is the object’s speed at point B? Express your answer using two significant figures. \( \upsilon_B = \) ____ m/s Submit button with a request answer option. ### Part B What is the object’s speed at point C? Express your answer using two significant figures. \( \upsilon_C = \) ____ m/s Submit button with a request answer option. ### Figure Description The figure shows a graph with potential energy \( U \) (in joules) on the vertical axis and position \( x \) (in meters) on the horizontal axis. The graph contains the following data points: - Point A: \( x = 0 \, \text{m},\, U = 10.0 \, \text{J} \) - Point B: \( x = 1.5 \, \text{m},\, U = 2.0 \, \text{J} \) (minimum point) - Point C: \( x = 3.5 \, \text{m},\, U = 5.0 \, \text{J} \) (a rise after a dip) - Point D: \( x = 4.5 \, \text{m},\, U = 2.5 \, \text{J} \) - Point E: \( x = 5.0 \, \text{m},\, U = 8.0 \, \text{J} \) The curve moves through these points, showing changes in potential energy as the object moves along the x-axis.
