Consider a head-on, elastic collision between a massless photon (momentum po and energy Eo ) and a stationary free electron.
a) Assuming that the photon bounces directly back with momentum p (in the direction of po ) and energy E, use conservation of energy and momentum to find p.
b) Verify that your answer agrees with that given by Compton's formula with theta = pi.

Elastic Collision lab. I'm trying to calculate velocity,
momentum, and kinetic energy in an elastic collision. The data I
have is this. I tried using these numbers to calculate velocity and
momentum but the results show momentum is not conserved as it
should be. Is that just error from measurements or am I missing
something?

(A): Consider a head-on, elastic collision between two bodies
whose masses are m and M, with m<<M. It is well known that if
m has speed v0 and M is initially at rest, m will bounce
straight back with its speed unchanged, while M will remain at rest
(to an excellent approximation). Use this fact to predict the final
velocities if M approaches with speed v0 and m is
initially at rest. (use Galilean transformation)
(B): Use the method of...
Consider a completely elastic head-on collision between two particles that have the same mass and the same speed.
Consider a completely elastic head-on collision between two particles that have the same mass and the same speed. What are the velocities after the collision? The magnitudes of the velocities are the same but the directions are reversed. One of the particles continues with the same velocity, and the other reverses direction at twice the speed. Both are zero. One of the particles continues with the same velocity, and the other comes to rest. More information is required to determine the final velocities.
