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 $2\mathrm{.}02{10}^4\frac{N}{C}?($b$)$ What speed would the proton attain if the field accelerated the proton through a distance of $1\mathrm{.}42cm?$
