As a person pushes a box across a floor, the energy from the person’s moving arm is transferred to the box, and the box and floor become warm. during this process, energy is .

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 = 1.6 ✕ 10−13 kg · m2/s2. based on this, what are the units of momentum for a high-speed subatomic particle in terms of fundamental si units?
