The correct answer is D.
We can use the formula F=ma, where F is the force applied, m is the mass of the object, and a is the acceleration.
Substituting the given values, we get:
F = (145 g) x (80 m/s^2)
Converting the mass to kilograms:
F = (0.145 kg) x (80 m/s^2)
F = 11.6 N
Therefore, the pitcher applied a force of 11.6 N to the baseball.
