Question

the passage below describes an experiment. read the passage and then follow the instructions below.
brittany had 12 soccer balls of equal size, all inflated to a pressure of ten pounds per square inch. she deflated six of the balls to a pressure of five pounds per square inch. she used a ball launcher to launch each soccer ball at a 30° angle, alternating between inflated and deflated soccer balls. brittany measured the distance between the ball launcher and the location where the ball hit the ground.
identify the question that brittanys experiment can best answer.
are balls easier for people to catch when the balls have a pressure of ten pounds per square inch or a pressure of five pounds per square inch?
do soccer balls that have a pressure of ten pounds per square inch travel farther when launched than soccer balls that have a pressure of five pounds per square inch?
do soccer balls travel farther when they are launched at a 30° angle or a 60° angle?

Explanation:

Brittany's experiment involves launching soccer balls with different pressures (ten pounds per square inch and five pounds per square inch) and measuring the distance they travel. The key variable here is the pressure of the soccer balls. The first option is about catching (not related to the experiment's measurement of distance). The third option is about launch angle (but the experiment uses a fixed \(30^{\circ}\) angle). The second option directly relates to the pressure variable (ten vs. five pounds per square inch) and the measured outcome (distance traveled).

Answer:

Do soccer balls that have a pressure of ten pounds per square inch travel farther when launched than soccer balls that have a pressure of five pounds per square inch?
