(choose chapter or problem)

Note: Answers to all odd-numbered Problems, numbered in blue, can be found in Appendix III. Exercises in the Problems by Topic section are paired, with each odd-numbered problem followed by a similar even-numbered problem. Exercises in the Cumulative Problems section are also paired but more loosely. Because of their nature, Challenge Problems and Conceptual Problems are unpaired.

A metal with a threshold frequency of \(6.71 \times 10^{14} \mathrm{~s}^{-1}\) emits an electron with a velocity of \(6.95 \times 10^{5} \mathrm{~m} / \mathrm{s}\) when radiation of \(1.01 \times 10^{15} \mathrm{~s}^{-1}\) strikes the metal. Calculate the mass of the electron.
