An electron travels at speed [v] = 0.995c, where c = 3x 108 m/s is the speed of light. It travels in the direction given by the unit vector = . The mass of an electron is 9x10-31 kg. (a) What is the value of y - (Tulle) ? You can simplify the calculation if you notice that (u/e) = = 0.995. (b) What is the speed of the electron? (c) What is the magnitude of the electron's momentum? (d) What is the vector momentum of the electron? Remember that any vector can be "factored" into its magnitude times its unit vector, so that = 0.
