Final answer:
The force exerted by the baseball player on a 0.15 kg baseball accelerated at 2000 m/s² is 300 Newtons.
Step-by-step explanation:
To calculate the force exerted by the baseball player on the ball, we use Newton's second law, which states that force equals mass times acceleration (F = ma). Given that the mass (m) of the baseball is 0.15 kg and the acceleration (a) is 2000 m/s², the force (F) exerted can be calculated by multiplying these two values.
So, the force exerted by the baseball player on the baseball is:
F = m × a
F = 0.15 kg × 2000 m/s²
F = 300 N
Therefore, the force exerted on the baseball by the player is 300 Newtons.
