    Momentum/KE Problem

    A neutron with a mass of 1.67×10^−27 kg and moving with a speed of 45000 m/s makes a head-on collision with a boron nucleus with a mass of 1.66×10^−26 kg. The boron nucleus is originally at rest. If the collision is perfectly elastic, what fraction of the neutron's original kinetic energy is...
