Question
**Conservation of Energy, Projectile Motion, Acceleration x, y, z**

A marble of weight = 5 lb is launched thanks to a spring on a ramp.

The spring has a coefficient of rigidity of k = 5 lb/ft, an unstretched length of s0 = 7 ft.

The ramp is l = 9 ft long and h = 5 ft tall.

![diagram]

In the diagram:

- A spring (denoted by the symbol K) is compressed and launches the marble up a ramp.
- The ramp is inclined and leads to point A, where the marble has a velocity \( v_A \).
- The point A is the beginning of the projectile motion path.
- The path from point A to point C shows the projectile trajectory of the marble with a parabolic shape.
- Point B represents the maximum altitude \( h_{\text{max}} \) of the marble’s flight.
- The horizontal distance from point A to point C is labeled as the Range.

**Given:**
If the velocity at A is \( v_A = 9 \) ft/s, find:
1. The displacement of the spring needed to reach this velocity.
2. The range of the flight.
3. The maximum altitude of the flight.

**Instructions for solving the problems:**

1. **Displacement of the Spring:**
   - Use energy conservation principles to connect the spring displacement to the launch velocity \( v_A \).

2. **Range of the Flight:**
   - Use projectile motion equations to find the range. This involves decomposing the launch velocity into horizontal and vertical components.

3. **Maximum Altitude of the Flight:**
   - Use kinematic equations to find the maximum altitude.

**Example Equations:**
1. Spring Potential Energy: \( \frac{1}{2} k x^2 \)
2. Kinematic Equations for Projectile Motion.
3. Energy Conservation: Potential Energy of the Spring = Kinetic Energy at A.

**Input Instructions:**

In the box below, enter the maximum altitude of the flight in ft with 2 decimals (Question 3).

---

**Note on the Diagram:**

- The inclined plane (ramp) is marked with its length and height.
- The spring is shown compressed at the bottom of the ramp.
- The trajectory from A to C is a dashed curve, indicating the parabolic path of the projectile.
- Arrows and labels indicate key quantities to be calculated
