Given information

It is given that the reaction is  .

Step-by-step explanation

Step 1.
 
 

Initially the total momentum is zero. So, from the conservation of momentum.  After the reaction the two product have equal magnitude of momentum but the direction is opposite.

We assume that the reactants are at rest when they react, so the total momentum of the system is 0 . As a result, the momenta of the two products are equal in magnitude.

Since, the available energy of   is much smaller than the masses involved,

Therefore, the nonrelativistic relationship between momentum and kinetic energy has to be use.
   
 
After rearranging,
