Answer 1

To find the force applied by the pitcher to the baseball, we can use Newton's second law of motion, which states that force (F) equals mass (m) multiplied by acceleration (a).

F = m * a

Given:
Mass of the baseball (m) = 145 g = 0.145 kg (since 1 kg = 1000 g)
Acceleration (a) = 80 m/s²

Plugging in the values into the formula, we get:

F = 0.145 kg * 80 m/s²
F = 11.6 kg·m/s² = 11.6 N

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