A wheel of radius 6cm is mounted so as to rotate about a horizontal axis through its centre. A string of negligible mass wrapped round its circumference carries a mass of 200g attached to its free end. When allowed to fall, the mass descends through 100cm in 5 seconds. Calculate the angular acceleration of the wheel, its moment of inertia and the tension in the cord.
