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...
