Two masses, each 25 kg, are connected by a cord and frictionless pulley. You give the mass a push to the left, and let go. At the moment you release the mass, it is moving at a speed of 3.5m/s to the left. The mass slides across a table and stops, the coefficient of kinetic friction between the mass and the table is 0.22. Draw a force diagram for each mass (AFTER, you release it, but before it stops).

A device known as Atwoods machine consists of two masses hanging from the ends of a vertical rope that passes over a pulley. Assume the rope and pulley are massless and there is no friction in the pulley. Mass mA is greater than mass me. Find expressions for the magnitude of their acceleration, a, and the tension in the rope, T. Express your answers in terms of the masses and g, the acceleration due to gravity.
