The mechanical advantage (MA) of an inclined plane can be calculated using the formula:
\[ \text{MA} = \frac{\text{Length of the Incline}}{\text{Height of the Incline}} \]
In your case, the length of the incline is 30 meters and the height is 2 meters. Plugging in these values:
\[ \text{MA} = \frac{30 , \text{meters}}{2 , \text{meters}} = 15 \]
So, the mechanical advantage of the inclined plane is \( MA = 15 \).
