To measure the static friction coefficient between a 4.96-kg block and a vertical wall, the setup shown in the drawing is used. A spring (spring constant = 491 N/m) is attached to the block. Someone pushes on the end of the spring in a direction perpendicular to the wall until the block does not slip downward. If the spring in such a setup is compressed by 0.0579 m, what is the coefficient of static friction? Number i Units m

Body U with mass 5m is stacked on the top body W with mass m, and released. The bodies are in contact along the frictionless interface at 45° to the vertical. The body U is in contact with the frictionless vertical wall. Body W lies on the floor with coefficient of friction u. Relevant dimensions are shown in the figure. Express the results in terms of given quantities: m, g, h and µ (except when µ is given numerically). You need not evaluate sin 45° = cos 45° = 2/2. h U: 5m C 45 D W: m 3h
You are working in an ice skating rink and have been asked to hang a new banner on the wall. Your friend is helping you so that the ladder does not collapse by exerting a force F_AL at an angle ϕ relative to the horizontal. The ladder has a length L and makes an angle of θ with respect to the vertical wall. You have a mass, m_Y, and are a horizontal distance x from the wall. The ladder has a mass of m_L. Because the wall is slick, and the ice on the floor is slick, the frictional forces acting on the ladder are negligible. Find a formula for the magnitude of the force that your friend must exert to keep the ladder from falling, in terms of the following variables: x,L,m_Y,m_L,θ,ϕ. Then use the following values to get a number for the magnitude of F_AL. θ = 30.3 degrees ϕ = 23.028 degrees x = 1.491 meters L = 7.1 meters m_Y = 86.0 kg m_L = 42.14 kg Find the magnitudes of: F_AL, normal force of the wall on the ladder (N_WL), and normal force of the floor on the ladder (N_FL).

1 A person exercises the quadriceps as shown. The diagram on the right shows a model of the leg, where the person's lower leg of length L = 0.60 m is held at an angle 0₁ = 60° with respect to the horizontal. The quadriceps muscle exerts a force FM via the tendon that attaches to the tibia at a distance d = 0.10 m from the knee, in order to lift a weight of mass m₁ = 5.91 kg that is attached to the foot. The tendon makes an angle of 0₂ = 11.5° with respect to the tibia. 2 What is the force required to hold the weight at the position shown in the diagram? Assume the person's lower leg weighs 150 N and its centre of mass is located at a distance L/2 from the knee. Round your answer to the nearest Newton. FM M d- 02 01 m₁
