a lever has a mechanical advantage of 4. if you apply force to the machine with a mass of 4 kg, at an acceleration of 2 m/s/s, what is the alpha first grade by the lever? Hint: use the equation FO= MA*Fi

The equation FO = MA * Fi relates the output force (FO), mechanical advantage (MA), and input force (Fi).

Given that the mechanical advantage (MA) is 4, and the input force (Fi) is the force applied to the machine, we need to calculate the output force (FO).

The formula to calculate force is F = m * a, where F is force, m is mass, and a is acceleration.

Given that the mass (m) is 4 kg and the acceleration (a) is 2 m/s^2, we can calculate the force (Fi) applied to the machine as:
Fi = m * a
Fi = 4 kg * 2 m/s^2
Fi = 8 kg m/s^2

Now, we can substitute the values into the equation FO = MA * Fi:
FO = 4 * 8 kg m/s^2
FO = 32 kg m/s^2

Therefore, the output force (FO) exerted by the lever is 32 kg m/s^2.
