A propeller consists of two blades each 4.0 m in length and mass 126 kg each. The propeller can be approximated by a single rod rotating about its center of mass. The propeller starts from rest and rotates up to 1,180 rpm in 30 seconds at a constant rate. (Enter the magnitudes.) (a) What is the angular momentum (in kg · m2/s) of the propeller at
t = 10 s?
