Hi.
The energy required to accelerate an object of mass ##m## to a speed ##v## is ##E_k=\frac{m}{2} v^2##. But how much energy does an object need to accelerate itself to ##v##? Say, how much fuel (in energy units) does a car need to accelerate to ##v##, if there are no air resistance or friction losses? Is it still ##E_k=\frac{m}{2} v^2##? How do you calculate that, as the car's rest frame ist not inertial?
