A barbell is mounted on a nearly frictionless axle through its center. The low-mass rod has a length d = 0.22 m, and each
ball has a mass m = 0.1 kg. At this instant, there are two forces of equal magnitude F applied to the system as shown in
Figure 11.107, with the directions indicated, and at this instant the angular velocity is 80 radians/s, counterclockwise, and
the angle θ = 35°. In the next 0.004 s, the angular momentum relative to the center increases by an amount 3.5 × 10−4 kg
m2/s. What is the magnitude of each force?
