Final answer:
The Physics question asked about calculating mechanical advantage, velocity ratio, and output work for a five-pulley system lifting a 650N load with a 300N effort. The mechanical advantage is 5, the velocity ratio is also 5, and the output work is 2600 Joules.
Step-by-step explanation:
The subject of this question is Physics, specifically the topic of mechanical advantage and pulley systems. Given a five-pulley system and an effort of 300N to lift a load of 650N up to 4m, we are asked to calculate the mechanical advantage (MA), velocity ratio (VR), and output work. The mechanical advantage for pulleys is calculated by counting the number of ropes supporting the load. Therefore, the mechanical advantage (MA) of a five-pulley system would be 5, since there are five ropes supporting the load. The velocity ratio (VR) can be calculated as the distance of effort travel divided by the distance of load travel. In this case, to lift the load 4m, you would have to pull 20m of rope (5 ropes times 4m), so VR = 20/4 = 5. The output work (work done on the load) is the product of the load force and the distance the load is moved, which is 650N × 4m equaling 2600 Joules, assuming no energy is lost due to friction.
