To find the force applied to the baseball, we can use Newton's second law of motion, which states:
\[ F = m \cdot a \]
where:
- \( F \) is the force,
- \( m \) is the mass,
- \( a \) is the acceleration.
First, we need to convert the mass from grams to kilograms, as the standard unit of mass in the International System of Units (SI) is kilograms:
\[ m = 145 , \text{g} = 0.145 , \text{kg} \]
Next, we have the acceleration:
\[ a = 80 , \text{m/s}^2 \]
Now we can substitute the values into the formula:
\[ F = 0.145 , \text{kg} \times 80 , \text{m/s}^2 \]
Calculating this gives:
\[ F = 11.6 , \text{N} \]
Thus, the amount of force the pitcher applied to the baseball is 11.6 N.
