SUMMARY
The discussion centers on the dynamics of a rotating cylinder with a radius of 0.1m and an initial angular velocity of 10 revolutions per second, placed on horizontal ground. The coefficient of friction is 0.1, and the objective is to determine the time it takes for the cylinder to roll without slipping. The correct answer is established as 2.09 seconds, with clarification that the initial frequency provided was the standard frequency rather than angular frequency. Key equations utilized include F=ma and M=J ⋅ ∝.
