Consider the system shown in Fig. 4-62 with mA = 9.5 kg and mB = 11.5 kg. The angles θA = 59∘ and θB = 32∘, (a) In the absence of friction, what force F→ would be required to pull the masses at a constant velocity up the fixed inclines? (b) The force F→ is now removed. What is the magnitude and direction of the acceleration of the two blocks? (c) In the absence of F→, what is the tension in the string? FIGURE 4-62 Problem 86.

Consider the system shown in Fig. 4-62 with $m_{A} = 9.5 k g$ and $m_{B} = 11.5 k g$ . The angles $θ_{A} = 59^{\circ}$ and $θ_{B} = 32^{\circ}$ , (a) In the absence of friction, what force $\vec{F}$ would be required to pull the masses at a constant velocity up the fixed inclines? (b) The force $\vec{F}$ is now removed. What is the magnitude and direction of the acceleration of the two blocks? (c) In the absence of $\vec{F}$ , what is the tension in the string?
