A proton $($mass m $=1\mathrm{.}67$ x $10^-27)$ is being accelerated along a straight line at $1\mathrm{.}00$x$10^12$ m$/$s$^2$ in a machine. If the proton has an initial speed of $1\mathrm{.}9$x$10^5$ m$/$s and travels $3\mathrm{.}30$ cm$,$ what then is $($a$)$ its speed and $($b$)$ the increase in its kinetic energy?
