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 A

What is the angular momentum of the bar about the axle?

Step 1

Given

Angular velocity ω = 120 rev/min

Length of the bar L = 2.0 m

Mass m = 480 g = 0.480 kg

Step 2

Solution

Moment of inertia of the bar

Step 3

Angular velo...
