A photon moving in the +x-direction, scatters off afree stationary electron. The wavelength of the incident photon is0.0330 nm. After the collision, the electron moves at an angleα below the +x-axis, while the photon moves at anangle θ = 73.3° above the +x-axis. (For thepurpose of this exercise, assume that the electron is travelingslow enough that the non-relativistic relationship between momentumand velocity can be used.)
(a)
What is the angle α (in degrees)?
° counterclockwise from the +x-axis
(b)
Determine the speed of the electron (in m/s).
m/s
