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).
