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. 32 N
c. 0.5 N
d. 0.5 J
To solve this problem, we can use the equation Fo = MA * Fi, where Fo represents the output force, MA represents the mechanical advantage, and Fi represents the input force.
Given that the mechanical advantage is 4, we can substitute this value into the equation:
Fo = 4 * Fi
We also know that the input force can be calculated by multiplying mass (m) with acceleration (a), as Fi = m * a. Plugging in the given values of mass (4 kg) and acceleration (2 m/s^2):
Fi = 4 kg * 2 m/s^2
Fi = 8 N
Now we can substitute the value of Fi into the equation for Fo:
Fo = 4 * 8 N
Fo = 32 N
Therefore, the output force created by the lever is 32 N.
The correct answer is b. 32 N.
