Answer 1

To find 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, and \( a \) is the acceleration.

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

2. Use the acceleration provided: \[ a = 80 \text{ m/s}^2 \]

3. Now, apply the formula: \[ F = m \cdot a = 0.145 \text{ kg} \cdot 80 \text{ m/s}^2 \]

4. Calculate the force: \[ F = 0.145 \cdot 80 = 11.6 \text{ N} \]

So, the correct answer is 11.6 N.
