Answer :
Final answer:
The batter swinging the bat impacts the baseball, changing its direction and velocity. This involves the principles of physics, particularly momentum and the laws of motion.
Explanation:
This question involves the principles of physics, specifically momentum and the laws of motion. When a batter swings a bat and it makes contact with a baseball, the direction and speed of the baseball is changed. This is due to the transfer of momentum from the bat to the ball. The baseball, which had a mass of 0.145 kg and was initially moving in a direction opposite to the swung bat (which is the -z direction here), will experience a force due to the impact and its velocity and direction will change according to the angle and force with which the bat made contact.
