Photoelectrons with a maximum speed of 8.00 * 107 m/s are ejected from a surface in the presence of light with a frequency of 7.50 * 1014Hz. If the mass of an electron is 9.10 * 10-31 kg, calculate the maximum kinetic energy of a single electron, in joules.
7.28 * 10-23 J
5.82 * 10-15 J
2.91 * 10-15 J
3.41 * 10-16 J
