The 480 gg bar is rotating as shown in (Figure 1).
You may want to review (Pages 271  274) . Figure
1 of 1The figure shows a bar rotating around an axle in its midpoint with frequency of 120 revolutions per minute. The axle is perpendicular to the bar. The length of the bar is 2.0 meters.

Part AWhat is the angular momentum of the bar about the axle?

Given
Angular velocity ω = 120 rev/min
Length of the bar L = 2.0 m
Mass m = 480 g = 0.480 kg
Solution
Moment of inertia of the bar
Angular velo...
