Compound Pendulum Angular Acceleration
A compound pendulum has a moment of inertia of I = 2.0 kg·m² about its pivot, and its center of mass is located 0.5 m from the pivot. If the pendulum is displaced from equilibrium by an angle of θ = 0.1 rad, what is the magnitude of its initial angular acceleration?
A
0.98 rad/s²
B
0.49 rad/s²
C
4.9 rad/s²
D
0.245 rad/s²
