Two racquetballs, each having a mass of 170 g, are placed in a glass jar asshown. Their centers lie on a straight line that makes a 45 degree angle with thehorizontal. a) Assume the walls are frictionless and determine P1, P2 and P3. b)Determine the magnitude of the force exerted by the left ball on the right ball.

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.
