Question:

In the system shown in Figure P5.31, a horizontal force Fx acts on the 8.00-kg object. The horizontal surface is frictionless.
(a) For what values of Fx does the 2.00-kg object accelerate upward?
(b) For what values of Fx is the tension in the cord zero?
(c) Plot the acceleration of the 8.00-kg object versus Fx. Include values of FX from ─100 N to + 100 N.
