what is the mass of a moving car at 100m\h?

Question

it dosn't madder the type of car

Answer 1

Are you sure you mean mass?

I think at 100 meters per hour (or even miles per hour if that's what you mean) you can discount any relativistic effects and say that the mass at 100 m/h is the same as it's mass when it's standing still.

It will matter what type of car it is though, because how fast it's going doesn't effect the weight but you're going to have to know how much it weighs in the first place and all cars weigh different amounts.

Answer 2

Essentially the same as if it were standing still. There is a correction arising from special relativity, but in the case of a car it is far too small to be of interest.

Answer 3

this question does not make sense at all, for you have a lot of unknown variables. if i say "i am moving at a speed of 100 m/s will you be able to answer that question? of course no. because you dont know the momentum, kinetic energy, etc..... get it?

Answer 4

its impossible to know unless you find out the force of the car
