Final answer:
The question pertains to the optimal angle of projectile motion for hitting a target with a baseball. It is a Physics concept demonstrating that a projectile at 45 degrees has the maximum range on level ground, but a ball hurled at 30 degrees would require a complementary angle of 150 degrees to hit the same target again.
Step-by-step explanation:
The subject of the question relates to the optimal angle for projectile motion to ensure it hits a target. According to physics, a projectile launched at 45 degrees above the horizontal typically achieves the maximum range on level ground, assuming no air resistance. However, the question asks about a ball hurled at 30 degrees, while in a different example, one is launched at 60 degrees. The range of the projectile depends on the initial speed, and the angle of launch relative to the horizontal, and since no other external factors (like wind resistance or air pressure) are mentioned, we can infer it's an ideal physics scenario.
To hit the target, the baseball must be thrown at angles that complement the angle it was hurled at originally; these are mirror angles with respect to the vertical. So, if a baseball launched at 30 degrees can hit a target, it can also hit the target if it is thrown at an angle of 150 degrees (180 - 30 degrees). The options provided do not include this angle. However, a ball thrown straight up at 90 degrees will come down to the same point if not impacted by any other force.
