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 .6 meters. If the plane has a
mechanical advantage of 2.3, how long is the plane?
3.83 m
1.38 m
2.9 m
1.84 m
To find the length of the inclined plane, we can use the formula:
Length of inclined plane = Vertical distance / Mechanical advantage
Length of inclined plane = 0.6 m / 2.3 = 0.26 m
Therefore, the length of the inclined plane is 1.38 meters.
So the correct answer is: 1.38 m
