Question

The system shown in the figure below is used to lift an object of mass m = 21.5 kg. A constant downward force of magnitude F is applied to the loose end of the rope such that the hanging object moves upward at constant speed. Neglecting the masses of the rope and pulleys, find the following. (a) Find the required value of F. N (b) Find the tensions T1, T2, and T3. (T3 indicates the tension in the rope which attaches the pulley to the ceiling.) T1 = N T2 = N T3 = N (c) Find the work done by the applied force in raising the object a distance of 2.60 m. J
