Question

In the system shown in the figure below, a horizontal force Farrowboldx acts on an object of mass m2 = 7.70 kg. The horizontal surface is frictionless. Consider the acceleration of the sliding object as a function of Fx.
(a) For what values of Fx does the object of mass m1 = 3.30 kg accelerate upward? (Indicate the direction of the force with the sign of your answer. Let the positive x direction be to the right.)
Fx > N

(b) For what values of Fx is the tension in the cord zero? (Indicate the direction of the force with the sign of your answer. Let the positive x direction be to the right.)
Fx ? N

(c) Plot the acceleration of the m2 object versus Fx. Include values of Fx from ?100 N to +100 N. (Do this on paper. Your instructor may ask you to turn in this work.).

Explanation / Answer

a) For Fx > 32.34 Newtons m1 will have an upward acceleration. 3.3 * 9.8 = 32.34 b) For Fx
