A light rope is attached to a block with mass 3.00 kg that rests on a frictionless, horizontal surface. The horizontal rope passes over a frictionless, massless pulley, and a block with mass m is suspended from the other end. When the blocks are released, the tension in the rope is 15.3 N . part a) Draw free-body diagram for the 3.00-kg block. Assume block is moving to the right. Draw the vectors starting at a black dot. The location...

A wooden block with mass 0.37 kg rests on a horizontal table, connected to a string that hangs vertically over a friction-less pulley on the table's edge. From the other end of the string hangs a 0.12 kg mass. What minimum coefficient of static friction μ s between the block and table will keep the system at rest? Find the block's acceleration if μ k =0.20.

A block A with a mass of 3 kg rests on a horizontal table top. The coefficient of kinetic friction, μk = 0.5. A horizontal string is attached to A and passes over a massless, frictionless pulley, and block B with mass 2 kg hangs from it. Because of the pull of gravity, the masses accelerate. What is the Tension in the string (in Newtons)?

Block A in (Figure 1) has mass 1.00 kg, and block
B has mass 3.00 kg. The blocks are forced together,
compressing a spring S between them; then the system is
released from rest on a level, frictionless surface. The spring,
which has negligible mass, is not fastened to either block and
drops to the surface after it has expanded. The spring has force
constant 711 N/m and is initially compressed 0.225 m from its
original length.
