The Conservation of Momentum Equation. A 0.400 kg bead slides on a straight frictionless wire and moves with a velocity of 0.035 m/s to the right. The
bead collides elastically with a larger 0.600 kg bead that is initially at rest. After the collision, the smaller
bead moves to the left with a velocity of 0.007 m/s. What is the large bead's velocity after the collision?

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.
