Given: A flywheel within large water pump is a solid disk with mass 20.5 kg and a radius of 0.44 m. Starting from rest it begins to rotate with a constant acceleration of 2.3 rad/sec2 for 5.1 sec after which it rotates at a constant rate.
Question: What is the magnitude of the total linear acceleration of a piece of metal on the very outer edge of the flywheel 4.1 seconds after it started to rotate?
