If the mass is released from rest and falls a distance of 0.5 m in 1.5 s,

*Mass of wheel = 3 kg*

Outside radius of wheel = 300 mm

Radius of gyration = 212 mm

calculate:

(a) The linear acceleration of the mass. For this I got0.22ms^-2

(b) The angular acceleration of the wheel. For this I got 1.467 rad s^-2

(c) The tension in the rope. 4.96N

(d) The frictional torque, resisting motion. Providing my answers are correct for a, b and c how do I solve d? Also if someone can confirm my work till now is correct please that would be great.......
