1.) what maximum speed will an alpha particle reach if it moves from rest through a potential difference of 7.5 x 10^3 V? The charge of an alpha particle is 3.2 x 10^-19 C and the mass of an alpha particle is 6.65 x 10^-27 kg.

2.)An alpha particle with an initial speed of 7.15 x 10^4 m/s enters through a hole in the positive plate between two parallel plates that are 9.0 x 10^-2 m apart. If the electric field between the plates is 1.7 x 10^2 V/m, what is the speed of the alpha particle when it reaches the negative plate?
