Questions below are based on the following passage:
To launch tennis balls from varying angles and at different speeds, a student builds the catapult shown in Figure 1. The tennis ball is propelled out of the catapult with velocity and angle .
The student conducts two experiments to measure the distance between the launch site and where the ball lands. The student varies, launches the ball at a constant 15 m/s, and measures the distance travelled. The results are provided in Figure 2.
In the second experiment, the student varies the launch velocity of the ball, launches it at a constant angle, and measures the distance travelled. The measurements are recorded in Figure 3.
