A small table is placed in an elevator. A light, frictionless pulley is attached to the end of the table.Two masses are connected by a string that passes over the pulley; m1 = 3.0 kg rests on the table, and m2 = 2.0 kg hangs off the side. Between m1 and the table there is no friction. While the elevator begins moving, the masses are measured by observers in the elevator to have an acceleration of a′. (a) Find the...

Description: A single mass m1 = 3.9 kg hangs from a spring in a motionless elevator. The spring is extended x = 11 cm from its unstretched length. the spring constant of the spring is 347.45 N/m Now, three masses m1 = 3.9 kg, m2 = 11.7 kg and m3 = 7.8 kg hang from three identical springs in a motionless elevator. The springs all have the same spring constant that you just calculated above. the force the top spring...
