An atomic nucleus suddenly bursts apart (fission) into twa pieces. Piece A with mass ma travels to the left with a speed of va. Piece B with mass
mg travels to the right with speed vg. Show the velocity of piece B in terms of mĄ, mg and VA.
Solution
Consider that the nucleus is not acted by an external force. Thus, momentum is conserved, sc:
PBf + PAf = 0
Substituting the expression for momentum results to
mgv
MAV
= 0
Deriving the expression for the velocity of piece B results to
F(mA/m
NA
