Please Help!! Show work Please A 3 kg box is sliding across a flat floor at an initial speed of 2.0 m/s and comes to a stop in 3 meters. If the only force acting on the box is force of kinetic friction. Draw a force diagram of the box. What is the net force acting on the box? What is the coefficient of friction between the box and floor?​

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.
