### Problem Statement: Motion of a Crate on an Inclined Ramp

You managed to pull a heavy crate up a ramp on a truck. The crate has a mass of 48 kg. You were pulling with 464 N of force along the ramp while the ramp made an angle of θ = 29.5 degrees with the horizontal. The coefficient of kinetic friction between the crate and the ramp is 0.45.

What is the acceleration of the crate along the ramp?

#### Diagram:
Below is a diagram illustrating the scenario described:

- The ramp is inclined at an angle θ with the horizontal.
- The crate is being pulled up the ramp.
- The force applied (F_A) is along the surface of the ramp. This force is indicated with a vector pointing upwards along the ramp.

#### Explanation of Forces and Motion:
1. **Gravity (Fg)**: Acts downward with a magnitude of \( F_g = m \cdot g \) (where \( m = 48 \) kg and \( g = 9.81 \) m/s²).
2. **Normal Force (N)**: Acts perpendicular to the surface of the ramp.
3. **Applied Force (F_A)**: The force pulling the crate up the ramp (464 N).
4. **Frictional Force (F_f)**: Opposes the motion, governed by the coefficient of kinetic friction (μ_k = 0.45).
5. **Components of Gravity**: 
   - Parallel to the ramp: \( F_{g,\parallel} = F_g \sin(\theta) \)
   - Perpendicular to the ramp: \( F_{g,\perp} = F_g \cos(\theta) \)

#### Calculation Steps:
1. **Calculate the component of gravitational force parallel to the ramp**:
   \[
   F_{g,\parallel} = m \cdot g \cdot \sin(\theta)
                  = 48 \, \text{kg} \cdot 9.81 \, \text{m/s}^2 \cdot \sin(29.5^\circ)
   \]
   
2. **Calculate the component of gravitational force perpendicular to the ramp**:
   \[
   F_{g,\
