Need help with 8 and 9 please thanks.
8) A pulley has two suspended masses hanging down on each side in a classic Atwoods machine. If 15.0 kg is on the right and 9.00 kg is on the left, what is the tension force and acceleration of the system? 9) An object sits at the edge of a table top with a mass of 143 kg. It is connected by a fine strong thread to a mass via a pulley which is hanging in the air below the edge of the table top. The friction coefficient between the 143 kg mass and the table is 0.300 and the tension in the thread is 890. N, find the acceleration of the system and the mass of the other block!!

    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?

    Please show all work, equations used, and free body diagram. Two masses are connected by a string (ignore the mass of the string), one is on an incline and the other is being suspended by a pulley in the air (Pulley is also massless and frictionless). The higher object (m1) is 5 kg and is sitting on the incline and is experiencing friction. The incline is 20 degrees from the horizontal and has a coefficient of kinetic friction Uk=0.35. The...

    A laboratory on the concept of static equilibrium uses an apparatus called a force table. The force table consists of a round, level platform marked in degree increments about its circumference. In the center of the table sits a massless ring, to which three strings are tied. Each string is strung over a separate pulley clamped to the edge of the platform, and then tied to a freely-hanging mass, so that each string is under tension and the ring is...
