To calculate the force applied to the baseball, we can use Newton's second law of motion, which states that \( F = m \cdot a \), where:

  • \( F \) is the force,
  • \( m \) is the mass of the object,
  • \( a \) is the acceleration of the object.

First, we need to convert the mass of the baseball from grams to kilograms:

\[ 145 \text{ g} = 0.145 \text{ kg} \]

Next, we can plug the values into the formula:

\[ F = m \cdot a = 0.145 \text{ kg} \cdot 80 \text{ m/s²} \]

Calculating this gives:

\[ F = 0.145 \text{ kg} \cdot 80 \text{ m/s²} = 11.6 \text{ N} \]

Thus, the force applied by the pitcher to the baseball is 11.6 N.
