Function escape_velocity_kernel 

pub fn escape_velocity_kernel(
    mass_primary: &Mass,
    radius: &Length,
) -> Result<Speed, PhysicsError>

Calculates escape velocity: $v_e = \sqrt{\frac{2GM}{r}}$.

Arguments

• mass_primary - Mass of the primary body $M$.
• radius - Distance from center of mass $r$.

Returns

• Ok(Speed) - Escape velocity $v_e$.
