A body of mass 2kg is moving with a constant velocity of 4m/s in x direction. Another body of mass 3kg is moving with a constant velocity of 1m/s in minus x direction. After collision they both combine with each other and move in x direction and some sound energy is produced.Find the value of the sound energy

THEORY RELATED TO QUESTION: above question is an case perfectly inelastic collision 
sound energy is produced becouse of heat loss in collision 
heat loss formula  :    1 (m1 m2 ) ( v1 – v2 )2
                                           2(m1+ m2)
 
using above formula, we can directly solve the problem 
m1 = 2 kg
m2=   3 kg
v1 =  4 m/s
v2 =  -1 m/s
v1 – v2 = 5 m/s 
after solving you will get 15 J
