Answer 1

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.
