A wheel of radius 8 cm is attached to a support so as to rotate about a horizontal axis through its centre. A string of negligible mass wrapped around its circumference carries a mass of 0.4 kg attached to its free end. When the mass is released, it descends through 1 m in 10 seconds, then its moment of inertia is
(Acceleration due to gravity = 10 ms−2)
