A force is exerted directly up on the axle of a pulley. Consider the
pulley and string to be massless and the pulley has no friction. Two
objects: with mass 1.2 kg and with mass 1.9 kg are
attached to the opposite ends of the string which passes over the
pulley. The object is in contact with the floor.
a) What is the largest value the force may have so that
will remain at rest on the floor?
b) What is the tension in the string if the upward force F is 110 N?
c) With the tension found in part b, what is the acceleration of ?
