Answer 1

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 of the baseball from grams to kilograms:

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

Next, we can plug in the values into the equation:

\[ F = 0.145 \text{ kg} \cdot 80 \text{ m/s}^2 \]

Now, calculating that:

\[ F = 0.145 \cdot 80 = 11.6 \text{ N} \]

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