Answer 1

The mechanical advantage (MA) of an inclined plane can be calculated using the formula:

$$\text{Mechanical Advantage (MA)}=\frac{\text{Length of the Inclined Plane}}{\text{Height of the Inclined Plane}}$$

In this case, the length of the inclined plane is 9 feet, and the height is 3 feet. Plugging these values into the formula gives:

$$\text{MA}=\frac{9\text{ feet}}{3\text{ feet}}=3$$

Thus, the mechanical advantage of the inclined plane is 3.
