Answer:
Explanation:
We shall apply law of conservation of Ā momentum in space to know the velocity of combination after the impact
māvā = māvā
.1 x 4 = ( 1 + .1 ) vā
vā = .3636 m /s
1 Ā ) Ā
Kinetic energy of the combination
= 1/2 x 1.1 x ( .3636)²
= 7.3 x 10ā»Ā² J
2 )
Initial kinetic energy of the system
= 1/2 x 0.1 x 4²
= 0.8 J
Final Ā kinetic energy of the system = 7.3 x 10ā»Ā²
Loss of energy = .8 - .073
= .727 J
This energy was converted into internal energy of the system .
3 )
increase in entropy = dQ / T
Here dQ = .727 J
T Ā = 300 ( Constant )
dQ / T = 2.42 X 10ā»Ā³ J/K
