1. The problem statement, all variables and given/known data A flywheel and shaft have a moment of inertia of 600kg and is rotating at 5 rev/s. Another flywheel and shaft, on the same axis, is suddenly connected by means of a clutch. If this flywheel and shaft has a moment of inertia of 620kg and is initially at rest, calculate: a) The common speed of rotation after the two are connected b) The loss in kinetic energy Answer is attached in document... But i need to describe the law of conservation of momentum and showing where it is used in this calculation and i need to describe what would the consequence for my calculations were the law of conservation not to be true.... Its for a practice exam paper and i seriously need some help? thanks!!
