QUESTION 4 An atomic nucleus suddenly bursts apart (fission) into two 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 ma, mg and VA- Solution: Consider that the nucleus is not acted by an external force. Thus, momentum is conserved, so: PBr+ PAF=0 Substituting the expression for momentum results to mgv mAV = 0 Deriving the expression for the velocity of piece B results to =(ma/m NA

QUESTION 4
An atomic nucleus suddenly bursts apart (fission) into two 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 ma, mg and VA-
Solution:
Consider that the nucleus is not acted by an external force. Thus, momentum is conserved, so:
PBf + PAf = 0
Substituting the expression for momentum results to
mgv
mAV
= 0
Deriving the expression for the velocity of piece B results to
=(ma/m
WA
V
