A small metal ball with a mass of 5.3 g and a charge of 6.3 mC is located at a distance of 0.70 m above the ground in an electric field of 14 N/C directed to the east. The ball is then released from rest. What is the velocity of the ball after it has moved downward a vertical distance of 0.30 m? (Assume that the +x direction is east, the +y direction is north, and the +z direction is upward.)
