0.65 kg and its length is 0.55 m. What is the rotational energy of the blade at its operating angular speed of 3450 rpm ?
Express your answer using two significant figures.
Part B
If all of the rotational kinetic energy of the blade could be converted to gravitational potential energy, to what height would
the blade rise?
Express your answer using two significant figures.

this is an example of "committed" time.
