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.

Two masses are connected by a massless rope. The mass of object 1 is 5.5 kg, and it rests on a surface with a 1.7 coefficient for static friction (us) and a .90 coefficient for kinetic friction (uk). Object 2 has a mass of 8.3 kg and hangs over the edge of the surface by a frictionless, massless pulley. The two objects begin at rest when object 2 is released to hang freely. A.)
