What does the scale read (in N) when (a) the elevator is at rest, (b) the elevator is climbing at a constant speed of 3.0 m/s, (c) the elevator is descending at an acceleration of 1.9 m/s', (d) the elevator is ascending at an acceleration of 1.2 m/s?? Pulley 13. An Atwood Machine is a pulley with two weights hung vertically over each side of the pulley. If we neglect any friction and the mass of the pulley, find the tension in the cord and the acceleration of each mass when they are released and in motion. Draw free-body diagrams for each mass. m1 14. Block A is on a smooth frictionless surface and is connected to Block B, which hangs vertically by a thin thread. Draw free-body diagrams for each block and then find the acceleration of the system and the tension in the connecting thread. Assume the pulley is frictionless and small.
