Homework Statement
A Particle (x) of relative mass of 4 is emitted from a uranium 238 nucleus. Assuming the the particle (x) was originally at rest and was emitted with a speed of 1.4E7 m/s.
calculate the recoil speed of the residual nucleus (thorium 234)
Homework Equations
none given
The Attempt at a Solution
I know this is to do with the conservation of momentum. so P1=P2
p2=m2v2
so for particle (x) : (4*1.66E-27)*(1.4E7) = 9.296E-20 kgm/sbut initial velocity is 0 and i don't know how to go about calculating the recoil on the uranium nucleus? I am kinda lost..
can anyone help me out?
