The height of the inclined plane is 2 m, and its length is 4 m. To lift a load weighing 1.8 kg along this inclined plane, a force of 25 N was required. Find the efficiency of the inclined plane.
1) According to the formula efficiency of an inclined plane, efficiency = (Ft * h / Fz * S) * 100%; Ft = mg; => Efficiency = (mg * h / Fz * S) * 100%
2) Efficiencynp = (1.8kg * 10m / s ^ 2 * 2m / 25N * 4m) * 100% = 36%
Answer: 36%.
