A block is resting on an inclined plane as shown in the figure below. Static friction between the block and the plane prevents the block from sliding. (Please write legibly. Typing answers is highly suggested.) Draw a free-body diagram for the block. Label all forces acting on it, making sure the relative size of each force is approximately correct. Apply Newton's 2^nd law by writing two equations: one for the forces that lie parallel to plane, and the other for...

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...
