SUMMARY
The discussion centers on determining the safety of parking on icy driveways with varying inclines. The driveways in question have inclines of 13°, 8°, and 5°, with a coefficient of static friction of 0.15 between tire rubber and ice. Through calculations involving the forces acting on the car, it is established that only driveways with inclines less than or equal to 8.6° are safe for parking. Therefore, Ralph's (8°) and Bonnie's (5°) driveways are safe, while the 13° incline is not.
