Answer 1

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

1. Convert the mass of the baseball from grams to kilograms:
   \[ 145 , \text{g} = 0.145 , \text{kg} \]

2. Use the acceleration given (80 m/s²) and the mass in kilograms to calculate the force:
   \[ F = m \times a = 0.145 , \text{kg} \times 80 , \text{m/s}^2 \] \[ F = 11.6 , \text{N} \]

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