A rotating cylindrical rod of mass m=4 Kg and length l=1 meter is connected to a falling weight of 300 grams with a 2 meters string (Maximum distance covered by the falling weight). The distance from the wound string to the axis of rotation is 300 mm. The time taken by the falling weight to halfway is 2 seconds and to the bottom is 2.7 seconds.

If we replace the 300-gram falling weight with the 2 Kg weight, it takes 1 seconds to reach to the halfway mark and 1.5 seconds to the bottom.

A propeller consists of two blades each 3.6 m in length and mass 108 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 1,210 rpm in 30 seconds at a constant rate. (Enter the magnitudes.) What is the angular momentum (in kg · m2/s) of the propeller at t = 10 s?
