Salut Richard ! Tu dis que la vitesse apparente est =C3=A9gale =C3=A0:
> Vapp=3DVo/(1+cos=C2=B5.Vo/c)
Comment est-elle reli=C3=A9e =C3=A0 la vitesse radiale: vr =3D vs cos =CE=
=B8, o=C3=B9 =CE=B8 est l'angle form=C3=A9 par la ligne de vis=C3=A9e vers =
le mobile et la trajectoire de celui-ci. ? https://wikimonde.com/article/Vi=
tesse_radiale .
Quel est l=E2=80=99inter=C3=AAt de d=C3=A9finir une nouvelle vitesse ?=20
Et comment peux-tu rattacher un temps =C3=A0 une vitesse fictive ? Ce sera =
forc=C3=A9ment un temps fictif.
