Beams of high-speed protons can be produced in "guns" using electric fields to accelerate the protons. (a) What acceleration would a proton experience if the gun's electric field were $2.00 \times 10^4 \mathrm{~N} / \mathrm{C}$ ? (b) What speed would the proton attain if the field accelerated the proton through a distance of $1.00 \mathrm{~cm}$ ?
$1.92 \times 10^{12} \mathrm{~m} / \mathrm{s}^2 $
