Context: The passage below describes an experiment. Read the passage and then follow the instructions below.

Luther placed a ping pong ball in a catapult, pulled the catapult's arm back to a 45° angle, and launched the ball. Then, Luther launched another ping pong ball, this time pulling the catapult's arm back to a 30° angle. With each launch, his friend Roy measured the distance between the catapult and the place where the ball hit the ground. Luther and Roy repeated the launches with ping pong balls in four more identical catapults. They compared the distances the balls traveled when launched from a 45° angle to the distances the balls traveled when launched from a 30° angle.

Identify the question that Luther and Roy's experiment can best answer.
A. Do ping pong balls travel farther when launched from a 30° angle compared to a 45° angle?
B. Do ping pong balls stop rolling along the ground sooner after being launched from a 30° angle or a 45° angle?
Choose the right answer from the options and respond with its letter.
