8) Is it possible for an object to move at constant speed without a force pulling or pushing it?*
A) No, a constant force is needed to keep an object moving at a constant speed.
B) No, a force is needed to keep an object moving at constant speed, but it doesn't

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.
