Special relativity (composition of velocities) Calculator

Calculates the composition of two velocities.

Velocity of a body A v1
    1. km/s
    2. ≦c
Velocity of a body B v2
    1. km/s
    2. ≦c

Composition of velocities v
    1.  
    2. km/s
The compound velocity v does not exceed the velocity of light c.

Bug report
If you input 0.8c and 0.6*c, or 0.8*c and 0.6*299792.458, it gives 179,875.4748

but if you input 0.8*299792.458 and 0.6*299792.458, or 0.8*299792.458 and 0.6*c, it gives 283,587.46027027, which is the correct value

so something seems to be borken with 0.8*c
