A block‑and‑tackle system consists of one fixed pulley and one movable pulley. A load of 200 N is attached to the movable pulley. The effort is applied by pulling the rope at an angle of \(30^{\circ}\) to the vertical. The rope has a weight of \(0.05\ \text{N m}^{-1}\). The point of application of the effort moves a distance of 1.20 m at a constant speed of 0.90 m s\(^{-1}\). (i) Find the speed of the load, and (ii) the mechanical power supplied by the effort.

Answer Options

A. Load speed = 0.90 \\text{m s}^{-1}; Power supplied ≈ 208 \\text{W}
B. Load speed = 0.60 \\text{m s}^{-1}; Power supplied ≈ 130 \\text{W}
C. Load speed = 0.30 \\text{m s}^{-1}; Power supplied ≈ 70 \\text{W}
Correct Answer D. Load speed = 0.45 \text{m s}^{-1}; Power supplied ≈ 104 \text{W}
Correct Answer
D
Correct Option:
Load speed = 0.45 \text{m s}^{-1}; Power supplied ≈ 104 \text{W}
