054 O In Fig. 15-49a, a metal plate is mounted on an axle through its center of mass. A spring with k = 2000 N/m connects a wall with a point on the rim a distance r= 2.5 cm from the center of mass Initially the spring is at its rest length. If the plate is rotated by 7° and released, it rotates about the axle in SHM, with its angular position given by Fig. 15-49b.The horizontal axis scale is set by t, = 20 ms. What is the rotational inertia of the plate about its center of mass? e (deg) t (ms) 10 (a) (6)
