Final answer:
To find the force exerted by a baseball, multiply its mass (1.25 kg) by its acceleration (35 m/s^2), resulting in a force of 43.75 newtons.
Step-by-step explanation:
The force exerted by a baseball can be calculated using Newton's second law of motion, which states that force equals mass times acceleration (F = ma). Given that the mass of the baseball is 1.25 kg and it is accelerating at a rate of 35 m/s2, the force exerted by the baseball can be found by multiplying its mass by its acceleration.
F = ma
F = (1.25 kg)(35 m/s2)
F = 43.75 N
Therefore, the baseball exerts a force of 43.75 newtons.
