51. Energy and momentum are conserved. We assume the residual thorium nucleus is in
its ground state. Let
K
α
be the kinetic energy of the alpha particle and
K
Th
be the kinetic
energy of the thorium nucleus. Then,
Q = K
+ K
Th
. We assume the uranium nucleus is
initially at rest. Then, conservation of momentum yields 0 =
p
+ p
Th
, where
p
is the
momentum of the alpha particle and
p
Th
is the momentum of the thorium nucleus.
Both particles travel slowly enough that the classical relationship between momentum
