A photon moving in the +x-direction, scatters off a free stationary electron. The wavelength of the incident photon is 0.0350 nm. After the collision, the electron moves at an angle a below the +x-axis, while the photon moves at an angle 0 = 70.3° above the +x-axis. (For the purpose of this exercise, assume that the electron is traveling slow enough that the non-relativistic relationship between momentum and velocity can be used.) (a) What is the angle a (in degrees)? ° counterclockwise from the +x-axis (b) Determine the speed of the electron (in m/s). m/s
