You and your team are designing a device that creates a beam of high-velocity protons. The device consists of a parallel-plate capacitor in which protons start at rest at the positive plate. The protons accelerate toward the negative plate, which has a hole through which some of the protons pass. The plates are separated by 6.0 cm, and the potential difference between the plates is 5.0 kV. What are

(a) The kinetic energies and

(b) The speeds of the protons when they pass through the hole?

(c) What is the acceleration of the protons between the plates?
