일반물리학 1 — Rolling, Torque, and Angular Momentum: Problem 6

6 Figure 11-23 gives the speed \( v \) versus time \( t \) for a \( 0.500\text{ kg} \) object of radius \( 5.75\text{ cm} \) that rolls smoothly down a \( 30^\circ \) ramp. The scale on the velocity axis is set by \( v_s = 4.0\text{ m/s} \). What is the rotational inertia of the object?
