A free body of mass 8 kg is travelling at 2 meter per second in a straight line. At a certain instant, the body splits into two equal parts due to internal explosion which releases 16 joules of energy. Neither part leaves the original line of motion finally
Text Solution

As the body splits into two equal parts due to internal explosion therefore momentum of system remains
conserved
i.e. 
⇒ ⇒ 
…(i)
By the law of conservation of energy
Initial kinetic energy + Energy released due to explosion
= Final kinetic energy of the system
⇒ ⇒ 
⇒ ⇒ 
…(ii)
By solving eq. (i) and (ii) we get 
and 
i.e. one part comes to rest and other moves in the same direction as that of original body.
