What would the mass be of a spaceship weighing 100 tons and be moving at 10% the speed of light , and will it be enough to bend spacetime or gravity. And increase its speed further like warping almost

100 tons, if you are discussing rest mass — it doesn't change. If you want to talk about total energy, then you want (gamma)mc² and at v = 0.1c, gamma is 1.005, in the frame of an observer who sees the rocket moving at 0.1c.

It's mass would be 90909.1 kg.( 100 tons at 2000 lbs to the ton and 2.2 lbs to the Kg) IOW, its mass would not change.

If you mean what the mass equivalence of its kinetic energy at 0.1c would be, that would be ~458 kg or ~ 1/2 of a percent of its rest mass.

It would only gain 1/2 of a ton in mass equivalence.

Ultimate Theory? Discussion of the concept of relativistic mass aside, even if that works don't trust any other links there. Crackpot central.
