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

A. 3.1 m
B. 1.5 m
C. 1.84 m
D. 0.35 m

1 answer

To determine the length of the inclined plane, we can use the formula for mechanical advantage:

MA = length of incline / 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 incline:

length of incline = MA * vertical distance
length of incline = 2.3 * 0.8
length of incline = 1.84 meters

Therefore, the length of the inclined plane is 1.84 meters. The answer is C. 1.84 m.
