An ideal block‑and‑tackle system has 4 supporting rope segments. It is used to lift a load of \(480\text{N}\). The operator applies a constant input force of \(150\text{N}\) and pulls the rope through a distance of \(2.5\text{m}\) in \(5.0\text{s}\). The system works with an overall efficiency of \(80\%\). (a) Calculate the vertical distance through which the load is raised. (b) Determine the power output of the system in watts.

Answer Options

A. a) \(1.0\text{m}\); b) \(90\text{W}\)
B. a) \(0.75\text{m}\); b) \(75\text{W}\)
Correct Answer C. a) \(0.625\text{m}\); b) \(60\text{W}\)
D. a) \(0.5\text{m}\); b) \(48\text{W}\)
Correct Answer
C
Correct Option:
a) \(0.625\text{m}\); b) \(60\text{W}\)
