A 7.6 −kg box having an initial speed of 4.5 m/s slides along a rough table and comes to rest.

A 7.6 −kg−kg box having an initial speed of 4.5 m/sm/s slides along a rough table and comes to rest.

Estimate the total change in entropy of the universe. Assume all objects are at room temperature (293 KK).

Express your answer to two significant figures and include the appropriate units.

If the question is right, we can find the total energy lost (-76.95 J) divide by the room temperature 293 K. So the change of entropy will be: -0.26 J/K
