Rope between inclines A rope rests on two platforms which are both inclined at an angle...
two blocks are positioned on surfaces, each inclined at the same angle of 49.4 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 4.61 kg, and the coefficient of kinetic friction for both blocks and inclines is 0.470. Assume static friction has been overcome and that everything can slide....
A block of mass 3.0 kg rests on an inclined plane that makes an angle withthe horizontal of 25◦. If the maximum friction force between the block and the surfaceis 11.6 N, find the coefficient of static friction.

1. The figure shows a box with mass m1 on a frictionless plane inclined at angle ?1. The box is connected via a cord of negligible mass to another box with mass m2 on a frictionless plane inclined at angle ?2 (> ?1). The pulley is frictionless and has negligible mass and assumes that the setup is on the surface of the earth. a) Provide free-body force diagram for both boxes. b) What is the acceleration in terms of m1,...
A box rests without slipping on a tilted table. What forces act on it to keep it stationary? Pick the answers that are correct. A downward gravitational force, mg. A frictional force between the block and the table that is always the same, no matter the angle of the table or the mass of the block. A frictional force parallel to the table up to a maximum set by the coefficient of friction, the mass of the block, and the tilt...

The ladder has a uniform weight of 80 lblb and rests against the wall at B. If the coefficient of static friction at A and B is μμmu = 0.41, determine the smallest angle θ at which the ladder will not slip. Note: friction is on both the wall and the ground.
A solid sphere of uniform density starts from rest and rolls without slipping down an inclined plane with angle θ = 30o. The sphere has mass M = 8 kg and radius R = 0.19 m . The coefficient of static friction between the sphere and the plane is μ = 0.64. What is the magnitude of the frictional force on the sphere? Ff = N

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.)
