An alpha particle is a helium nucleus and therefore consists of two protons and two neutrons. Such particle has an initial velocity of +1.60*10^3 m / s x(hat) and enters a region where the electric field is E! = - 500. N / C x (hat).
a) How much time passes before the alpha particle comes to rest?
b) How far has the alpha particle traveled during this time?
