On average, old sow gets to be a diameter of 3.6 meters (12ft). It generally rotates a velocity of 2.7 m/s (6mph). If the water has a mass of 362.873kg (8000 lbs), What is the centripetal force created by old sow on an average day? Plz can i have the procedure and the answer? :)

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.
