Answer:
v = 24 m/s, rightwards
Explanation:
Given that,
The mass of TBT explosive = 5 kg
It explodes into two pieces.
One of the pieces weighing 2.0 kg flies off to  the left at 36 m/s. Let left be negative and right be positive.
The law of conservation of momentum holds here. Let v be the final speed of the remaining piece. So,

So, the final speed of the remaining piece is 24 m/s and it is in the right direction. 
 
        
             
        
        
        
Answer:
Amount of  Energy transferred 
Explanation:
Given:
Initial volume=V
Initial pressure=P
Final volume=2V
Final pressure=3P
Now w know that the Energy transferred in constant pressure pressure is given by

Now the Energy transferred in constant volume process is given by

The total Energy transferred is given by

 
        
                    
             
        
        
        
There must be a equal opposite reaction.
E=mv2
