Question
![Protons and neutrons (together called nucleons) are held
together in the nucleus of an atom by a force called the
strong force. At very small separations, the strong force
between two nucleons is larger than the repulsive electrical
force between two protons-hence its name. But the strong
force quickly weakens as the distance between the protons
increases. A well-established model for the potential energy
of two nucleons interacting via the strong force is
U = U₁[1 - e */*o]
where is the distance between the centers of the two
nucleons, xo is a constant having the value
Xo = 2.0 × 10-15 m, and U₁ = 6.0 × 10-¹¹ J.
Quantum effects are essential for a proper understanding of
nucleons, but let us innocently consider two neutrons as if
they were small, hard, electrically neutral spheres of mass
1.67 x 10-27 kg and diameter 1.0 × 10-15 m. Suppose
you hold two neutrons 9.0 × 10-15 m apart, measured
between their centers, then release them.
What is the speed of each neutron as they crash together? Keep in mind that both neutrons are moving.
