A lever has a mechanical advantage of 4. If you apply a force to the machine with a mass of 4 kg, at an acceleration of 2 m/s/s, what is the output force created by the lever? Hint: Use the equation Fo=MA*Fi. A. 32 J B. 0.5 J C. 0.5 N D. 32 N
To solve this problem, we need to use the equation Fo = MA*Fi, where Fo is the output force, MA is the mechanical advantage, and Fi is the input force.
Given:
Mechanical Advantage (MA) = 4
Mass (m) = 4 kg
Acceleration (a) = 2 m/s/s
We know that force (F) is calculated as mass multiplied by acceleration (F = m*a). The input force (Fi) can be calculated as Fi = m*a.
Fi = 4 kg * 2 m/s/s = 8 N
Now, we can use the equation Fo = MA*Fi:
Fo = 4 * 8 N = 32 N
Therefore, the output force created by the lever is 32 N.
The correct answer is D. 32 N.
