//A flywheel
omega0=41.888 //rad/sec
omega=29.322 //rad/sec
t=120 //sec
//Kinematic equation gives
alpha=(29.3224-41.888)/(120) //rad/sec^2
//Weight of flywheel
Wf=50000 //N
//Radius of gyration
k=1 //m
I=(50000/9.81) //kg-m^2
//(1) Retarding torque acting on the flywheel Tr
Tr=5096.84*0.1047 //N-m
//(2) Change in K.E.
C.K.E=(5096.84*((41.888^2)-(27.322^2)))/(2) //N-m The answer provided in the textbook is wrong
//(3) Change in its angular momentum
C.A.M=5096.84*(41.888-29.322) //N-sec
