A 2.4 mmmm -diameter sphere is charged to -4.5 nCnC. An electron fired directly at the sphere from far away comes to within 0.35 mmmm of the surface of the target before being reflected.What was the electron's initial speed? Express your answer in meters per second. At what distance from the surface of the sphere is the electron's speed half of its initial value? Express your answer in meters. What is the acceleration of the electron at its turning point? Express your answer in meters per second squared.
