Question

we know that the cart can not continue to accelerate for ever because of friction ,the air density and many other reasons.assume though it could continue to accelerate .if the speed of light is 300,000km/s then how long would it take our cart to reach that speed or velocity​

Answer 1

Answer:

Never, because nothing can travel with the speed of light(excluding space, i.e-matrix of time and space) because for traveling with that speed the mass should be zero and yea it's possible to travel faster than light but not by really traveling with that speed, actually it is possible if u can wrap or fold the matrix of time and space by some kind of energy and for that u need energy and negative energy that is not possible now(researchers had named it as bubble wrapping tech).

Hope I can get brainliest for typing it manually
