An electron is moving east in a uniform electric field of 1.55 n/c directed to the west. at point a, the velocity of the electron is 4.52×105 m/s pointed toward the east. what is the speed of the electron when it reaches point b, which is a distance of 0.395 m east of point a?

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
