To calculate the force applied to the baseball by the pitcher, you can use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration (F = m * a).
Given:
- Mass of the baseball (m): 145 g = 145/1000 kg = 0.145 kg (since 1 g = 0.001 kg)
- Acceleration (a): 80 m/s²
Plug in the values:
F = m * a
F = 0.145 kg * 80 m/s²
F = 11.6 N
Therefore, the force applied by the pitcher to the baseball is 11.6 Newtons (N).
