A 73 kg person is riding in a car moving at 20 m/s when the car runs into a bridge abutment. Calculate the magnitude of the average force (in Newtons) on the person if he is stopped by a padded dashboard that compresses an average distance of 0.16 m

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.
