A uniform disc of moment of inertia 1 kg m^2 rotates with a speed of 1

1.	A uniform disc of moment of inertia 1 kg m^2 rotates with a speed of 120 rpm, Calculate the torque required to stop the disc in 10 revolutions ?
Answer» Solution :`a =(omega^(2)-omega_(0)^(2))//2THETA -(2PI xx 2)^(2)//2 xx 2pi xx 10 =-1.256 rad s^(-2), tau = l ALPHA = 1.256 Nm`
