a super man I sitting on a tree 98m high with a he has rescued from a claws of a tiger. unfortunately the child shift and falls with an initial velocity of 0m/s supposed reached what was happened 2 second later and flow to catch the child at a speed of 39.2m/s find the time super man will fly before catching the child, and the distance super man fly to catch the child

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.
