Two protons (each with rest mass $m = 1.67 \times 10^{-27} \text{ kg}$) are initially moving with equal speeds in opposite directions. The protons continue to exist after a collision that produces an $\eta^0$ particle. The rest mass of the $\eta^0$ is $m_{\eta} = 9.75 \times 10^{-28} \text{ kg}$.

Step 1
We need to find the initial momentum of the two protons. Since they are moving in opposite directions with equal speeds, their momenta will cancel out, so the initial momentum is zero. Show more…

Two protons (m = 1.67 x 10^-27 kg) are initially moving with equal speed in opposite directions. They continue to exist after a head-on collision that also produces a neutral pion of mass 2.4x10^-28 kg. If all three particles are at rest after the collision, find the initial speed of the protons. Energy is conserved in the collision.

Two protons are released from rest when they are 2 x 10^-4 m apart. Find their speeds when they are 5 x 10^-14 m apart. The charge of a proton is 1.6 x 10^-19 C, and the mass of a proton is 1.67 x 10^-27 kg. The value of Co is 8.85 x 10^-12 N m^2/C^2.

Two protons are released from rest when they are 2 !! 10-14 m apart. Find their speeds when they are 5 !! 10-14 m apart. (e = 1.6 !! 10-19 C, mass of the proton = 1.67 !! 10-27 kg, ̵0 = 8.85 !! 10-12 C/N m)
