For a force applied at top of a cylinder rolling without slipping on horizontal surface: ( F - f = M a ) and torque about CM: ( (F + f)R = I \alpha )?? No – The force at top and friction both produce torques. Force F at top: torque = F·R (clockwise, assume positive). Friction at bottom: torque = f·R (if friction acts left, torque also clockwise? Check: friction at bottom to left produces counterclockwise torque. So sign differs.) 12 SA C
Do not plug in numbers early. Use algebra and calculus (differentiation/integration) to derive the final formula. This prevents rounding errors and reveals dimensional mistakes.
