A lawn mower has a flat, rod-shaped steel blade that rotatesabout its center. The mass of the blade is 0.65 kg and its length is0.55 m. (a) What is the rotational energy of the blade at its operating angular speed of 3500 rpm? (b) If all of the rotational kineticenergy of the blade could be converted to gravitational potentialenergy, to what height would the blade rise?

Question
A lawn mower has a flat, rod-shaped steel blade that rotates
about its center. The mass of the blade is 0.65 kg and its length is
0.55 m. (a) What is the rotational energy of the blade at its operating angular speed of 3500 rpm? (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?
