To find the force applied to the baseball, you can use Newton's second law of motion, which states that force is equal to mass times acceleration (F = m * a).
First, convert the mass of the baseball from grams to kilograms:
\[
145 \text{ g} = 0.145 \text{ kg}
\]
Now, use the formula to calculate the force:
\[
F = m \times a = 0.145 \text{ kg} \times 80 \text{ m/s}^2
\]
Now calculate the force:
\[
F = 0.145 \times 80 = 11.6 \text{ N}
\]
Therefore, the force that the pitcher applied to the baseball is **11.6 N**.
