Anyone do this detailed study?

Do you guys agree with itute's answer for question 2? They said option B, but option B isn't really correct coz it's not more massive at "high speed"; it's more massive at any speed that's not zero.

well A is wrong and so is D. In this case the most appropriate answer would be B, not saying that its the best answer ever but its the most correct out of B and C. C didn't mention the increase in mass while B did.

A and C are most definitely wrong. Why is D wrong?

Indeed, I also had D...

It's been a year since i last did special relativity so i might be wrong but, for D, E=gamma*m*c^2. The total energy-mass is dependent on 3 things, gamma rest mass and c^2. Saying that total mass-energy depends on gamma is not as accurate as saying it is proportional to gamma. It feels like it's saying that it only depends on gamma. Who knows maybe vcaa will give both B and D the mark

Yeah fair point I guess. I think A and C are definitely wrong and there are problems with both B and D. It's a fairly ridiculous question though really.
