Hi,
Is the linear momentum conserved in the presence of friction if i consider certain systems?
For instance: supposing my system is made up by a planet still in space, and an object with a certain initial speed: the total momentum, being the planet initially still, will be the mass of the object times it's initial speed.. If then the object gets in contact with the planet giving life to friction, will the momentum be conserved? if after the friction the object stops moving, will the planet obtain a certain speed such that the (planets mass + the objects mass) times the planets new speed = objects initial speed times the object initial mass?
thanks a lot in advance and sorry for the language inaccuracy (i'm italian infact)
