e,
Salut Richard ! et bonjour =C3=A0 tous-ses !
Ce n=E2=80=99est pas tr=C3=A8s courageux de ma part, c=E2=80=99est ce que j=
=E2=80=99ai trouv=C3=A9 apr=C3=A8s force cogitations, alors je vous en fais=
 part avant m=C3=AAme que =C3=A7a soit publi=C3=A9. Voyez quelle chance vou=
s avez!=20

Je compl=C3=A8te ce qu=E2=80=99a dit Hachel.=20

Lorsque v<<c, ces relations deviennent p =3D m v et Ec =3D m v=C2=B2/2, cel=

N.B. La vitesse v est la vitesse r=C3=A9elle, celle que Hachel nomme Vr.
