A neutron collides elastically with a helium nucleus (at rest initially) whose mass is four times that of the neutron. The helium nucleus is observed to scatter at an angle ₂ = 52° from the neutron's initial direction. The neutron's initial speed is 50000 m/s. Determine the angle at which the neutron scatters, ₁, measured from its initial direction. 8.92 What is the speed of the neutron after the collision? 50000 x m/s What is the speed of the helium nucleus after the collision? 0.246 × m/s Submit Answer
