Detailed Description

Base segment for takeoff and landing segments. Integrates equations of motion
    including rolling friction.
    
    Assumptions:
    Notes Regarding Friction Coefficients
    Dry asphalt or concrete: .04 brakes off, .4 brakes on
    Wet asphalt or concrete: .05 brakes off, .225 brakes on
    Icy asphalt or concrete: .02 brakes off, .08 brakes on
    Hard turf:               .05 brakes off, .4 brakes on
    Firm dirt:               .04 brakes off, .3 brakes on
    Soft turf:               .07 brakes off, .2 brakes on
    Wet grass:               .08 brakes off, .2 brakes on
