a 45kg gymnast wedges himself between two closely spaced vertical walls by pressing his hands and feet against the walls. What is the magnitude of the friction force on each hand and foot? Assume they are all equal. Express your answer with the appropriate units.
Your friend asks for help moving a box across the apartment floor and tells you that the box weighs 422 N. Your friend also informs you the box, currently motionless, has a coefficient of static friction (us=0.42) and a coefficient of kinetic friction (u=0.31) between it and the floor. You apply a horizontal force of 208 N on the box. Calculate the magnitude of the frictional force, f, acting on the box while you apply that force. Take the acceleration of gravity to be 9.81 m/s². f = O Search N 7:59 PM 11/29/2022
A 4.00 kg box sits atop a 10.0 kg box on a horizontal table. The coefficient of kinetic friction between the two boxes and the lower box and table is 0.600, while the coefficient of static frction between these same surfaces is 0.800.

A block is pressed against a vertical wall by a force F , as the drawing shows. This force can either push the block upward at a constant velocity or allow it to slide downward at a constant velocity. The magnitude of the force is different in the two cases, while the directional angle 0 is the same. Kinetic friction exists between the block and the wall, and the coefficient of kinetic friction is 0.320. The weight of the block is 51.0 N, and the directional angle for the force F is 0 = 44.0°.

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.
