Gce Model Questions Vol1 2025 Physics Question 6
Practice essay / theory question 6 from the 2025 Gce Model Questions Vol1 Physics examination. This question covers machines, simple machines, mechanical advantage, efficiency, friction .
A compound pulley system is shown in the diagram. A 20 kg block (A) is attached to one end of a light, inextensible rope. The rope passes over a movable pulley (P) which is itself attached to a 10 kg block (B). The free end of the rope is pulled vertically upward by a person (the effort). The person pulls the rope through a distance of 2.0 m, causing the 20 kg block to rise a vertical distance of 0.5 m. The rope and pulleys are assumed massless. The system experiences friction in the pulley axle that dissipates 5 % of the total input work. Using g = 9.8 m s⁻², answer the following:
