MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A uniform pole of weight 12.0 N is propped between the floor and the ceiling of a room. The height of the room is 2.86 m, and when the pole is in equilibrium, the friction force between the base of the pole and the floor is 18.5 N. The normal force on the pole from the floor is 35.0 N. (a) What is the length (in m) of the longest pole that can be propped between the floor and the ceiling and stay at rest? m (b) Find the coefficient of static friction between the pole and the ceiling.​
