Can an particle travel more than speed of light?
Suppose we give ring a linear velocity of 3c/4 (where c is speed of light). Now we also rotate it with rotational velocity of 3c/4. Consider object in space. Is the velocity of top most point of ring in 3c/4 + 3c/4 = 3c/2 greater than speed of light?
Note down: 1. Ring is made of a hypothetical material which do not tear down or break down. 2. We have enough energy to make object to give ring that much velocity.
P.S. I don't have its answer confirmed.

1 solution
instead of rotate , write roll ! also solution is that simplified rigid body dynamics is not applicable at light speeds !
