A crate of mass MM starts from rest at the top of a frictionless ramp inclined at an angle αα above the horizontal. Find its speed at the bottom of the ramp, a distance dd from where it started. Do this in two ways.

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?
