Aproton with mass 1.67×10−27kg is propelled at an initial speed of 3.00×105m/s directly toward a uranium nucleus 5.00 m away. the proton is repelled by the uranium nucleus with a force of magnitude f=α/x2, where x is the separation between the two objects and α=2.12×10−26n⋅m2. assume that the uranium nucleus remains at rest. what is the speed of the protonwhen it is 8.00*10^-10m from the uranium nucleus?

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?
