You and your friend Blake are putting new shingles on a roof pitched at 25°. You are sitting at the very top of the roof when Blake, who is at the edge of the roof 5.0 m away (measured along the roof slope), asks you for a 2.5 kg box of nails. You give the box a push so that it will slide down the roof to Blake. If the coefficient of kinetic friction between the box and the roof is 0.55, what initial speed does your push need to create for the box for it to come gently to rest right at the edge of the roof? (Hint: Use a tilted coordinate system, with x along the slope of the roof).

A block, initially at rest, has a mass m and sits on a plane inclined at angle theta. It slides a distance d before hitting a spring and compresses the spring by a maximum distance of xf.

Sally wants to hang up some decorations on the side of her house, so she props up a ladder of length L = 3m against a wall at an angle of θ = 50° with respect to the horizontal. The ground is somewhat icy, where the coefficient of static friction between the ground and the ladder’s feet is µ = 0.55; while the wall of her house can be considered frictionless. If Sally has a mass of 60kg and the ladder has a mass of 80kg, what is the max distance that she can climb up the length of the ladder without it slipping? You may assume the ground is perfectly flat, and the wall is perpendicular to the ground.
a 55 kg rock climber is in a lie-back climb along a fissure, with hands pulling on one side of the fissure and feet pressed against the opposite side. The fissure has width w = 0.20 m, and the center of mass of the climber is a horizontal distance d = 0.40 m from the fissure. The coefficient of static friction between hands and rock is m1 = 0.40, and between boots and rock it is m2 = 1.2. (a) What is the least horizontal pull by the hands and push by the feet that will keep the climber stable? (b) For the horizontal pull of (a), what must be the vertical distance h between hands and feet? If the climber encounters wet rock, so that m1 and m2 are reduced, what happens to (c) the answer to (a) and (d) the answer to (b)?
