Question
In the figure below, a horizontal force F a of magnitude 21.0 N is applied to a 3.47 kg psychology book, as the book slides a distance d = 0.500 m up a frictionless ramp at angle 0 = 30.0°. Can you help part A and b show all work
In the figure below, a horizontal force \( \vec{F_a} \) of magnitude 21.0 N is applied to a 3.47 kg psychology book, as the book slides a distance \( d = 0.500 \text{ m} \) up a frictionless ramp at angle \( \theta = 30.0^\circ \).

**Diagram Explanation:**
The diagram shows a psychology book on a frictionless ramp inclined at an angle \( \theta \) with a horizontal force \( \vec{F_a} \) applied. The book moves a distance \( d \) up the ramp.

**(a)** During that displacement, what is the net work done on the book by \( \vec{F_a} \), the gravitational force on the book, and the normal force on the book?

1. Incorrect Attempt: 3.647
2. Correct Answer: 0.592

*Work done on an object by a constant force is equal to the dot product of the force and the object's displacement. Work is also equal to the change in the kinetic energy.*

**(b)** If the book has zero kinetic energy at the start of the displacement, what is its speed at the end of the displacement?

1. No Response Provided
2. Correct Answer: 0.584 m/s

**Link:** [GO Tutorial](#)

This problem involves calculating work done and using principles of energy conservation to find the speed of the book at the end of the displacement.

# Physics Problem Flow Chart

### 1. Draw a Picture
- **Action:** Label which directions are positive (x- and y-), and label relevant quantities on the diagram.

### 2. Draw a Second Picture...
- **Action:** If you have BEFORE/AFTER situations, consider force additions, and create vector component diagrams.

### 3. Identify Explicitly Given Values
- **Action:** Write all given actual numbers in terms of variables. For previously calculated values, use values before rounding for significant figures.

### 4. Identify Implicitly Given Values
- **Action:** Identify wording that implies specific values, such as "at rest," "comes to a stop," "dropped," "smooth surface," and "constant velocity."

### 5. Identify the Required Quantity and Type of Problem
- **Action:** Look for keywords like "when," "how far," "how fast," etc. Determine the type of problem from the given and sought quantities.

### 6. Calculate/Convert Easily Derived Quantities
- **Example:** The x- and y-components of velocity/force vectors, or the force of gravity given the mass.

### 7. Find Relevant Equation(s)
- **Action:** Choose one that links the given quantities to the quantity you need to find.

### 8. Find a Second Equation...
- **Action:** If you’re missing a quantity needed to use an equation, draw up a plan on how to link the equations and quantities.

### 9. Solve for the Quantity Without Using Numbers
- **Action:** First cancel any quantities that are zero. Use algebra to isolate the quantity you need on one side of the equals sign. Verify with dimensional analysis.

### 10. Sub in Numbers on Paper
- **Action:** Ensure the units of each number are correct before substituting values into the equations.

### 11. Use a Calculator to Find Value
- **Tip:** Use as few presses of the “=” or “ENTER” button as possible. Maintain extra significant figures until the next step.

### 12. Write Conclusion Statement with Correct Sig Figs
- **Action:** Conclude in plain English with correct units.
