$1)$ A proton and a beta$-$minus particle carry the same kinetic energy. How does the speed of the proton compare to that of the beta$-$minus particle?

$2)$ The kinetic energy of a proton is $100$ times the energy of a beta$-$minus particle. How does the speed of the proton compare to that of the beta$-$minus particle?

$3)$ If the speed of an alpha particle is $0\mathrm{.}5$v$\backslash$beta $($half that of a beta$-$minus particle$),$ how does its kinetic energy compare to the kinetic energy of the beta$-$minus particle?
