5kg particle is atteched at a rim of arotating wheel of radius 2m. the wheel completes each revolution in 3 seconds. The total moment of inertia of the system(I partics+I wheel) is 2kg.m^2
A.determine the rotational kinetic energy of the system?
B.the work needed to stop the rotation?
C.how much torque is required to stop the rotation of the system in1.2second?
