Jessica says, "In an elastic collision the kinetic energy of the objects is conserved so that the total kinetic energy before the collision is the same as it is after the collision. Don't you agree, Josh?" Josh says, "Yes, I agree, but for an inelastic collision, momentum is not necessarily conserved and a heavier object will have a smaller change in momentum than a lighter object. If the masses are equal," he argues, "the momentum will be conserved in an inelastic collision."Who is right?a. Jessicab. Joshc. Bothd. None of them

An electron is ejected into a horizontal uniform e⃗ field at a parallel horizontal velocity of v0. assume the electron's initial position x0, initial velocity v0, time t, magnitude of electric field e, electron's mass m, and the magnitude of the electron's charge |e|. ignore the force that earth exerts on the electron. assume the e⃗ field is in the same direction as the initial velocity. part a define the equation for the electron's velocity. express your answer in terms of the variables v0, |e|, t, e, and m.
