The inclined plane below is being used to lift a box 7 ft.
The inclined plane has a mechanical advantage of 1.5. What is the length, x, of the inclined plane?
mechanical advantage = (length of ramp)/(height of ramp)
a
.25 feet
b
7.5 feet
c
2.5 feet
d
10.5 feet
To find the length of the inclined plane, we can rearrange the formula for mechanical advantage:
length of ramp = mechanical advantage * height of ramp
Substituting the given values:
length of ramp = 1.5 * 7 ft
length of ramp = 10.5 ft
Therefore, the length of the inclined plane, x, is 10.5 feet. The correct answer is option d.
