A net force of 1.6×10−15 N acts on an electron over a displacement of 5.0 cm, in the same direction as the net?

A net force of 1.6×10−15 N acts on an electron over a displacement of 5.0 cm, in the same direction as the net force. (a) What is the change in kinetic energy of the electron? (b) If the electron was initially at rest, what is the speed of the electron? An electron has a m of 9.1×10−31 kg. answer part a) in joules and partb) in meters/second. THANKS:)
