Question
In the system shown in the figure below, a horizontal force x acts on an object of mass m2 = 7.80 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 = 3.90 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.).
