6. A 90 kg gymnast wedges himself between two closely spaced vertical walls by pressing his hands and feet against the walls. What is the minimum force the gymnast must push with each hand and foot if the coefficient of kinetic friction is 0.64 and the coefficient of static friction is 0.78? Assume the force on each hand and foot are all equal.

A 60 kg rock climber has positioned himself as shown in the figure (with his hands on one side of a gap and his feet on the other side). Both friction and normal forces act on his hands and feet. The width of the gap, w, is 0.24 m and the climber's center of mass is a horizontal distance d 0.54 m from the gap. The coefficient of static friction = 0.48 between his hands and the rock and 2...

Question 1 1.5 pts A 56 kg rock climber has positioned himself as shown in the figure (with his hands on one side of a gap and his feet on the other side). Both friction and normal forces act on his hands and feet. The width of the gap, w, is 0.30 m and the climber's center of mass is a horizontal distance d = 0.37 m from the gap. The coefficient of static friction Mi = 0.45 between his...

A student presses a book between his hands, as the drawing indicates. The forces that he exerts on the front and back covers of the book are perpendicular to the book and are horizontal. The book weighs 32.7 N. The coefficient of static friction between his hands and the book is 0.381. To keep the book from falling, what is the magnitude of the minimum pressing force that each hand must exert?
