You are out on a hike and come across an unfortunate scene: a fellow hiker has fallen off a ledge. You happen to be carrying a long rope, and bravely decide to help. You tie the rope to a rock of mass mR=500 kgmR=500 kg and make your way over the ledge (see figure).
If the coefficient of static friction between the rock and the ground is μS=0.355μS=0.355, and your mass is mH=70.5 kgmH=70.5 kg, what is the maximum mass of the fallen hiker (mFmF) that the rock can hold so that you two can make it back up from the ledge? Assume that where the rope passes the ledge is frictionless and that the rope is parallel to the ground.

- Your answer is partially correct. A 2.20 kg block is initially at rest on a horizontal surface. A horizontal force of magnitude 4.22 N and a vertical force are then applied to the block (see the figure). The coefficients of friction for the block and surface are μ = 0.4 and MK = 0.25. Determine the magnitude of the frictional force acting on the block if the magnitude of P is (a) 10.0 N and (b)12.0 N. (The upward pull is insufficient to move the block vertically.)

- A 12 N horizontal force pushes a block weighing 5.0 N against a vertical wall . The coefficient of static friction between the wall and the block is 0.60, and the coefficient of kinetic friction is 0.40. Assume that the block is not moving initially. (a) Will the block move? (b) In unit-vector notation, what is the force on the block from the wall?arrow_forwardThe diagram shows a block of mass m = 3.50 kg resting on a plane inclined at an angle of 0 = 40° to the horizontal. The coefficient of static friction between the block and the plane is μstatic = 0.30, and the block is stationary but just on the point of sliding down the slope. Ff F₁ 3 mg N 0 The diagram shows the four forces acting on the block: an applied force F₁ acting perpendicular to the slope (in the -y direction), the block's weight mg, the normal reaction force N and the force of static friction, Ff. In this case, the force of static friction acts up the slope, opposing the tendency of the block to move down the slope. Find the the minimum magnitude of the applied force F₁ that can be exerted if the block is to remain stationary. Specify your answer by entering a number into the empty box below.arrow_forwardStudents are performing an experiment with the setup shown above, where a block of mass M sits on a horizontal table. The coefficient of kinetic friction between the block and the table is μk. The block is connected to a hanging object over a pulley. The pulley has negligible mass and friction. The string connecting the two is very light and does not stretch. The students add mass to the hanging object so that its mass is m, where m < M, and the block-hanging object system is released from rest. The hanging object falls for a distance h, at which point it collides with the ground and comes to rest. The block on the table keeps sliding and travels a total distance d before coming to rest. It does not reach the pulley, and d > h. During this experiment does the angular momentum of the block-hanging object system about an axis through the center of the pulley remain constant?
