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 find the output force created by the lever, we can use the equation Fo = MA * Fi, where Fo is the output force, MA is the mechanical advantage, and Fi is the input force.
Given that the mechanical advantage is 4, we can substitute MA = 4 into the equation:
Fo = 4 * Fi
To find Fi, we can use the equation Fi = ma, where m is the mass (4 kg) and a is the acceleration (2 m/s/s):
Fi = 4 kg * 2 m/s/s = 8 N
Now we can substitute Fi = 8 N into the equation to find Fo:
Fo = 4 * 8 N = 32 N
Therefore, the output force created by the lever is 32 N.
The correct answer is d) 32 N.
