**Problem 4: Work Done on a Suitcase Pulled Up a Ramp**

A luggage handler pulls a 25 kg suitcase up a ramp inclined at 20° above the horizontal with a force \( \vec{F} \) of magnitude 230 N that acts parallel to the ramp. The coefficient of kinetic friction between the ramp and the suitcase is \( \mu_k = 0.15 \). If the suitcase travels 4.00 m up the ramp, calculate the following:

**(a)** The work done on the suitcase by \( \vec{F} \).

**(b)** The work done on the suitcase by the gravitational force.

**(c)** The work done on the suitcase by the normal force.

**(d)** The work done on the suitcase by the friction force.

**(e)** The total work done on the suitcase.

**(f)** If the speed of the suitcase is zero at the bottom of the ramp, what is its speed after it has traveled 4.00 m up the ramp?

---

**Detailed Explanations:**

1. **The Drawing:**
   - A block (representing the suitcase) is shown on an inclined plane that makes a 20° angle with the horizontal.
   - Arrows indicate the different forces acting on the suitcase:
     - \( \vec{F} \): The force exerted by the luggage handler.
     - \( \vec{g} \): Gravitational force acting downward.
     - \( \vec{N} \): Normal force perpendicular to the plane.
     - \( f_k \): Kinetic friction force acting opposite to the direction of motion.

2. **Understanding the Forces:**
   - **Force \( \vec{F} \)**: Parallel to the ramp, with a magnitude of 230 N.
   - **Gravitational Force**: Contains two components: one parallel to the ramp (\( mg \sin \theta \)) and one perpendicular to the ramp (\( mg \cos \theta \)).
   - **Normal Force**: Acts perpendicular to the surface of the ramp.
   - **Friction Force \( f_k \)**: Opposes the movement, calculated as \( f_k = \mu_k N \).

3. **Work Calculations:**
   - **Work by \( \vec{F} \)** (\( W_F \)): \( W_F = F \cdot d \cdot \
