Question
The flywheel (a massive disk or ring used for storing energy as rotational kinetic energy) of an old fashioned steam engine was running at a constant angular speed, but then at t=0 the steam was shut off, and friction due to the bearings and the air gradually bring it to rest. During the spin-down, the angular velocity was observed to be (t) = 39.3s-1 - (1.98*10-4s-3)t2
this is the first part in five to this question, following the one question only rule i split it up.
What was the initial, constant angular speed in the revolutions per minute? (please show work)
Explanation / Answer
put t=0
the initial, constant angular speed= 39.3 s-1
