Aphoton moving in the +x-direction, scatters off a free stationary electron. the wavelength of the incident photon is 0.0250 nm. after the collision, the electron moves at an angle α below the +x-axis, while the photon moves at an angle θ 65.3° 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 α (in degrees)? o counterclockwise from the +x-axis (b) determine the speed of the electron (in m/s) m/s
