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 asatronaut is 6ft, 6in. tall, and the initial velocity of the ball is 30ft per second. the heigh s of the ball in feet is given by the equation s = -2.7^2 + 30t + 6.5, where t is the number of seconds after the ball was thrown. after how many seconds is the ball 16ft above the moon's surface?
