Atugboat pulls a small barge through a harbor. the propeller thrust minus the drag produces a net thrust that varies linearly with speed. the combined weight of the tug and barge is 3600 kn. the relationship between force and velocity is plotted below: determine the time required to increase the speed from an initial value v1 = 1.0 m/s to a final value v2 = 2.5 m/s. the time required to increase the speed from an initial value v1 = 1.0 m/s to a final value v2 = 2.5 m/s is s

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.
