If you throw a ball with speed 0.5c in a spacecraft with speed 0.8c, wouldn't the speed of ball exceed speed of light, as the speed of ball would be 1.3c?
No.
According to theory of relativity, the speed of ball is not 0.8c+0.5c=1.3c
but (0.8c+0.5c)/(1+0.8cx0.5c/c^2)=(13/14)c which is smaller than speed of light.
For the derivation, see section 4 of
