Question
Harold uses an inclined plane to move a washing machine from the sidewalk into his house. The vertical distance from the sidewalk to the house is 0.8 meters. If the plane has a mechanical advantage of 2.3, how long is the plane?(1 point)
Responses
3.1 m
3.1 m
1.84 m
1.84 m
1.5 m
1.5 m
0.35 m
To solve this problem, we can use the formula for mechanical advantage:
Mechanical Advantage = Length of Inclined Plane / Vertical Distance
Given that the mechanical advantage is 2.3 and the vertical distance is 0.8 meters, we can rearrange the formula to solve for the length of the inclined plane:
Length of Inclined Plane = Mechanical Advantage * Vertical Distance
Length of Inclined Plane = 2.3 * 0.8
Length of Inclined Plane = 1.84 meters
Therefore, the correct answer is 1.84 m.
