Compute the change in entropy of the universe

Reference no: EM13494514

Two cars traveling in opposite directions collide head on and are brought to rest. If each car has a mass of 1100. kg and is moving at a speed of 95 km/h, estimate the change in entropy of the universe as a result of the collision. Assume T = 20.?C.
