Chapter 5, Problem 23P

In the system shown in Figure P5.23, a horizontal force $\stackrel{\to }{F}$acts on an object of mass m₂ = 8.00 kg. The horizontal surface is frictionless. Consider the acceleration of the sliding object as a function of F_r. (a) For what values of F_r does the object of mass m₁ = 2.00 kg accelerate upward? (b) For what values of F_r is the tension in the cord zero? (c) Plot the acceleration of the m₂ object versus F₁. Include values of F_r from −100 N to +100 N.
