🚀 How to Use

Prerequisites

  • .NET 8.0 or later
  • Command line interface

Running the Application

  1. Navigate to the project directory:

    cd RocketVelocityCalculator

  2. Build and run the application:

    dotnet run

What Happens When You Run It

The application automatically calculates and displays:

  1. Time Setting: Shows t = 2 seconds
  2. Velocity Calculation: Demonstrates v = 3 × t²
  3. Position Calculation: Shows s = t³
  4. Formatted Output: Displays results in required format
  5. Data Type Information: Shows types used
  6. Error Handling Demo: Tests negative time validation

🧮 Mathematical Formulas

Velocity Formula

v(t) = 3t²

Where:

  • v(t): Velocity at time t (meters per second)
  • t: Time in seconds
  • 3: Constant coefficient

Position Formula

s(t) = t³

Where:

  • s(t): Position at time t (meters)
  • t: Time in seconds
  • Initial Condition: s(0) = 0 meters

Example Calculations for t = 2 seconds

Velocity Calculation

v(2) = 3 × 2²
v(2) = 3 × 4
v(2) = 12 m/s

Position Calculation

s(2) = 2³
s(2) = 8 meters

📊 Sample Output

=== Rocket Velocity and Position Calculator ===
Calculating rocket motion at t = 2 seconds

Step a: Time t is set to 2 seconds
Step b: Velocity calculation: v = 3 × 2² = 12 m/s
Step c: Position calculation: s = 2³ = 8 meters

Step d: Formatted output:
At t=2 seconds, velocity is 12 m/s and position is 8 meters.

Step e: Data types used:
Time (t): Double = 2
Velocity (v): Double = 12
Position (s): Double = 8

Step f: Error handling demonstration:
✓ Error handling works: Time -1 is invalid (negative)

Step g: All steps have been commented in the code
