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.) Draw a free body diagram for...

Two boxes with masses m and M rest on a horizontal surface. Each box is mounted on tiny rollers and moves with negligible friction. A force applied to m gives it an acceleration am. a) find the acceleration M undergoes if pushed by the same amount of force. b) the boxes have masses 2kg and 5 kg. A force on the lighter one gives it an acceleration of 2 m/s^2. Calculate the acceleration of the 5 kg box when it...

Two blocks with masses m1 and m2 are connected by a massless string over a frictionless pulley. Block 1 sits on a frictionless horizontal surface and block 2 sits on a plane inclined at an angle θ above the horizontal. The coefficient of friction between block 2 and the incline is µk. The pulley, which is a uniform disk, has a mass mp and a radius R. When you release the blocks, both blocks slide without the string slipping on...
