70. A pencil rests against a corner, as shown below. The sharpened end of the pencil touches a smooth vertical surface and the eraser end touches a rough horizontal floor. The coefficient of static friction between the eraser and the floor is , 0.60 The center of mass of the pencil is locate 7.3cm from the tip of the eraser a12.9 cm from the tip of the pencil lead. Find the minimum angle 0 for which the pencil does not...
Take a look at the textbook, Ch. 12, problem #70. Except, change
the location of the center of mass to 9.7 cm from the eraser and
change the distance of the center of mass from the pencil's lead
tip to be 11 cm. Finally, assume that the coefficient of friction
is 0.7. Now solve for the minimum angle such that the pencil won't
slip. Enter your answer in degrees.

Change the location of the center of mass to 7cm from the eraser
and change the distance of the center of mass from the pencils lead
tip to be 13.2cm. Finally, assume that the coefficient of friction
0.7. Solve for the minimum angle such that the pencil wont slip.
Enter answer in degrees.

18. A 4.00-m-long uniform ladder, weighing 180 N, rests against a smooth vertical wall with its base on a horizontal rough floor, a distance of 1.20 m away from the wall. The coefficient of static friction between the ladder and the floor is 0.200. How far up the ladder, measured along the ladder, can a 600-N person climb before the ladder begins to slip? Group of answer choices 2.71 m 1.26 m 4.56 m 1.50 m 1.05 m
A 5.0-m long, 15-kg uniform ladder rests against a smooth
vertical wall with the bottom of the ladder 3.0 m from the wall.
The coefficient of static friction between the floor and the ladder
is 0.38. What distance, measured along the ladder from the bottom,
can a 70-kg person climb before the ladder starts to slip?

The uniform 20 lb ladder rests on the rough floor at A for which the coefficient o static friction is mu_s = 0.8 and against the smooth wall at B. A horizontal for P is applied at the center of the ladder as shown. Sketch a Free Body Diagram of the ladder. Determine the minimum force required to get the ladder to move and state if the ladder slides or tips about point A.
5) A 5.0-m long, 12-kg, ladder rests against a smooth vertical wall with the bottom of the ladder 3.0 m from the wall. The coefficient of static friction between the floor and the ladder is 0.28. What distance measured along the ladder from the bottom, can a 60-kg person climb before the ladder starts to slip? Ans: 1.7 m
A uniform ladder 12 meters long rests against a vertical frictionless wall, as shown in the figure. The ladder weighs 400 N and makes an angle θ = 51° with the floor. A man weighing 874 N climbs slowly up the ladder. When he is 78 m from the bottom of the ladder, it just starts to slip. What is the coefficient of static friction between the floor and the ladder? 7.8 m
Question 2 (1 point) A 5.0-m long, 15-kg uniform ladder rests against a smooth vertical wall with the bottom of the ladder 3.0m from the wall. The coefficient of static friction between the floor and the ladder is 0.38. What distance, measured along the ladder from the bottom, can a 70-kg person climb before the ladder starts to slip? 3.3 m O 0.9 m O 1.7 m 2.5 m 4.1 m
