Final answer:
The mechanical advantage of the baseball bat, used by Rafael who applies 25 N of force, is 0.2, as the bat exerts a force of 5 N on the baseball.
Step-by-step explanation:
The mechanical advantage (MA) of a baseball bat is calculated by dividing the output force by the input force. Given that Rafael swings the baseball bat with a force of 25 N (input force) and the bat exerts a force of 5 N on the baseball (output force), the mechanical advantage can be calculated using the formula MA = Output Force / Input Force.
MA = 5 N / 25 N= 0.2 Therefore, the mechanical advantage of the baseball bat is 0.2. This means that the bat provides less force on the baseball than the force applied by Rafael, which indicates that in this case, the bat is not acting as a force amplifier.
