Calculate the maximum speed of a emitted electron, where the maximum kinetic energy of the emitted electron is 2.28*10,^-19j.

The kinetic energy of a molecule or a sample is equal to the mass of the substance multiplied by the square of teh velocity. The mass of electron is equal to 9.10938356 × 10-31 kilograms. The kinetic energy given is 2.28 *10^-19 J.Hence the velocity is equal to 500,291.28 m/s
