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
7.5 feet
b
0.25 feet
c
9.0 feet
d
2.5 feet
To find the length of the inclined plane, we need to rearrange the formula for mechanical advantage:
mechanical advantage = (length of ramp)/(height of ramp)
Given that the mechanical advantage is 1.5, and the height of the ramp is 0.25 feet,
1.5 = x / 0.25
To solve for x, we can multiply both sides of the equation by 0.25:
0.25 * 1.5 = x
0.375 = x
Therefore, the length of the inclined plane, x, is 0.375 feet.
Therefore, the correct answer is:
b) 0.375 feet
