Answer 1

To determine the force applied to the baseball, you can use Newton's second law of motion, which states that force equals mass times acceleration (F = m * a).

Given:

• Mass (m) = 145 g = 0.145 kg (since 1 kg = 1000 g)
• Acceleration (a) = 80 m/s²

Now, plug in the values:

\[ F = m \times a \] \[ F = 0.145 , \text{kg} \times 80 , \text{m/s}^2 \] \[ F = 11.6 , \text{N} \]

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