Always draw a Free Body Diagram (FBD). In contests, "fictitious forces" (like centrifugal or Coriolis forces) can simplify math when working in rotating or accelerating frames. B. The Energy & Momentum Approach
Famous for its "problems with solutions" format, specifically the chapters on conservation laws and "The Lagrangian Method."
I = (1/2)(1)(0.2)² = 0.02 kg m²
, the equations of motion are derived systematically using the Euler-Lagrange equation:
, the kinetic energy consists of both the translational kinetic energy of the CM and the rotational kinetic energy about the CM:

h=R+25R=75Rh equals cap R plus two-fifths cap R equals seven-fifths cap R
f = μN = 0.2(14.6) = 2.92 N
The normal force (N) is equal to the weight of the block minus the vertical component of the force:
