SUMMARY
The maximum angle at which Jeremy can safely walk on an icy sidewalk with leather shoes, which have a coefficient of friction of 0.3, is 16.7 degrees. To maintain stability on a 65-degree incline, the required coefficient of friction would need to be 2.14. These calculations are based on the frictional force equation Ff = μ(Fn), where Ff represents the frictional force, μ is the coefficient of friction, and Fn is the normal force. A free body diagram is essential for visualizing the forces at play in this scenario.
