a 2kg block moving with an initial speed of 5m/s slides on a rough table and stopped ny the force of friction. assuming that the table and air remain at 24 C, calculate the entropy change of the universe

Question

anonymous · Answer

Entropy is the amount of energy not available for work. The amount of energy dissipated, with constant temperature, will be the change in kinetic energy.

anonymous · Answer

The units of entropy are Joules/Kelvin  
Convert your constant temperature to Kelvin, then divide the change in kinetic energy by the temp. in Kelvin, your units for entropy will be J/K.
