A block attached to a spring is oscillating between point X (fully compressed) and point Y (fully stretched). The surface is frictionless. As the block moves from point X to O (spring relaxed), the spring does work W on the block. How much work does the spring do on the block as it moves from O to Y

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.
