An electron is moving east in a uniform electric field of 1.50 N>C directed to the west. At point A, the velocity of the electron is 4.50 * 105 m>s toward the east. What is the speed of the electron when it reaches point B, 0.375 m east of point A?

An astronaut on the moon throws a baseball upward. the astronaut is 6 ft, 6 in. tall, and the initial velocity of the ball is 3030 ft per sec. the height s of the ball in feet is given by the equation s equals negative 2.7 t squared plus 30 t plus 6.5s=−2.7t2+30t+6.5, where t is the number of seconds after the ball was thrown. complete parts a and b.
