Consider the system of two masses connected by weightless strings on the right: A box of mass m1=1kg sits on an inclined, frictionless surface with an angle of a = 30 degrees. A second mass hangs from the ceiling with an angle of q = 30 degrees. A string parallel to the inclined surface connects both masses. The system is in equilibrium and does not move.
1) Draw a free body diagram of mass 1 and mass 2 and label all forces. (6 points)
2) Calculate the tension in the rope connecting m1and m2.
Would the tension decrease, increase or stay the same if mass 2 were increased? (11 points)
3) What is the value of m2? (8 points)

Two masses are connected on a frictionless pulley. M1 = 9 kg sits on a frictionless horizontal surface and is connected to a spring with a spring constant of k = 250 N/m. M2 = 6kg and hangs off the edge of the surface. Initially, both masses are at rest and the spring is at its equilibrium. After the blocks are released, how fast will they be moving when mass 2 falls .1 m?

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...
