## Description

This MCP server provides a physics-based calculation engine for determining rider velocity and speed loss when traversing rail features. It uses friction and balance models to calculate approach speed, speed loss, and exit speed. Use `get_approach_velocity` to determine safe entry speeds, `calculate_speed_loss` to quantify friction impact, `get_exit_velocity` to predict final speeds, or `analyze_feature_efficiency` for a complete momentum analysis.

## Tools

### analyze_feature_efficiency
Provides a holistic overview of the rail's impact on rider momentum

### calculate_speed_loss
Quantifies how much speed is lost due to friction during the traversal

### get_approach_velocity
Determines the initial velocity required to safely enter a specific rail feature

### get_exit_velocity
Predicts the final speed of the rider once they have cleared the rail

## Prompt Examples

**Prompt:** 
```
What is the required approach speed for a 5m rail at a 10 degree angle with a 70kg rider using a board?
```

**Response:** 
```
The required approach speed is 4.2 m/s with a recommended safety buffer of 0.5 m/s.
```

**Prompt:** 
```
How much speed will I lose on a 10m rail at 5 degrees if I enter at 5 m/s with a 75kg rider on a jib?
```

**Response:** 
```
The total speed loss due to friction is 0.85 m/s.
```

**Prompt:** 
```
Calculate the exit speed if I enter a rail at 6 m/s and lose 1.2 m/s of speed.
```

**Response:** 
```
The final exit speed will be 4.8 m/s.
```

## Frequently Asked Questions

**How does the equipment type affect the calculation?**
The calculation adjusts friction resistance based on whether you use a `jib` or a `board`, as they have different contact surface areas.

**What is the difference between flat and kinked entry?**
A `flat` entry assumes a continuous level surface, while a `kinked` entry accounts for an immediate angular change which increases initial resistance.

**Can I get a full report of the rail impact?**
Yes, you can use the `analyze_feature_efficiency` tool to get a holistic overview including approach speed, speed loss, exit speed, and momentum retention.
