Find velocity of the electron as seen from laboratory frame

Reference no: EM13670869

A radioactive nucleus travels at a velocity 0.1c. When it decays it ejects an electron which has a velocity relative to the nucleus of 0.8c. Find the velocity of the electron as seen from the laboratory frame if:

(a) The electron is emitted in the same direction as the nucleus is moving,

(b) The electron is emitted in the opposite direction to the direction of travel of the nucleus.
