(II) A falling rock has kinetic energy KE just before striking the ground and coming to rest. What is the total change in entropy of rock plus environment as a result of this collision?
ANSWER:
Solution 40P
Step 1 of 2
Here we have to calculate the change in entropy of the environment after collision of a falling rock with the ground.
The rock has a kinetic energy of KE just before reaching the ground and both rock and environment are at temperature .
