A rope is wound on a circular disc of moment of inertia 0.1 kg . m^(2). A tangential force of 20 N on the rope rotates the disc about its axis. If the radius of the wheel is 0.1 m, calculate its acceleration. Now a mass of 2 kg is suspended at thelower end of the rope. What will be the angular acceleration? g = 10 m.s^(-2)

1.	A rope is wound on a circular disc of moment of inertia 0.1 kg . m^(2). A tangential force of 20 N on the rope rotates the disc about its axis. If the radius of the wheel is 0.1 m, calculate its acceleration. Now a mass of 2 kg is suspended at thelower end of the rope. What will be the angular acceleration? g = 10 m.s^(-2)
Answer» ANSWER :20 RAD.`s^(-2) , 16.7 rad .s^(-2)`
