So would it be appropriate to say that since the mass would become infinitely large, there could never be a force large enough to accelerate the mass to the speed of light as a = F/m?
Damnit I hate these questions :cry:
(sorry, forgot to post my attempts at the problems first)
For number 1 I'm assuming that it takes more gas for the car to accelerate than it does to keep a constant speed.
2. I really have no idea on this one, I barely know what the space arm is.
3. Ditto to number 2, the best idea I...
If anyone could answer even just one of the questions below I would really appreciate it.
1. Why do cars get better gas mileage at constant speed than they do with a lot of accelerating?
2. The space arm works in weightless conditions (actually called microgravity conditions). Why must it...
