The dimensions of the quantity kinetic energy, designated by K$,$ are kg $$ m$2/$s$2.$ It can be written in terms of the momentum p and mass m as

K $=$ p$2/2$m

What are the units of momentum in terms of fundamental SI units? $($Use the following as necessary: kg$,$ m$,$ and s$.)$

$[$p$]=$

$($b$)$

Force is measured in units of newtons, N$,$ where

$1$ N $=1$ kg $$ m$/$s$2.$

What are the units of momentum p in terms of a newton and another fundamental SI unit? $($Use the following as necessary: N$,$ m$,$ and s$.)$

$[$p$]=$

$($c$)$

What If$?$ Physicists often measure the momentum of subatomic particles moving near the speed of light in units of MeV$/$c$,$ where c is the speed of light, and

$1$ MeV $=1\mathrm{.}61013$ kg $$ m$2/$s$2.$

Based on this, what are the units of momentum for a high$-$speed subatomic particle in terms of fundamental SI units?

$[$p$]=$
