Astring is wrapped around a disk as shown at the right. a 0.3 kg 0k mass is attached to the lower end of the string and released from rest if the disk is free to rotate without friction and the string does not slip, find a. the moment of inertia of the disk. [0.9 kg m2l b. the magnitude and direction of the net torque on the disk. 0.6 m 1.6 n. m, n2pg] c. the magnitude and direction of the angular acceleration of the disk. 0.3 kg [1.8 rad/s2, n2pg] d. the downward acceleration of the mass [1.1 m/s? ] e. the tension in the string. [2.7 n f. the distance the object falls in 2 seconds. 12.1 m] g. the angular velocity of the disk at 3 seconds. [5.4 rad/s, n2pg]
