While building his catapult, Aiden tested several different designs. He varied the arm length of his catapult and recorded the horizontal distance between where the ball was launched and where it landed for each arm length.
The table presents Aiden’s data showing the length of the catapult arm in relation to the horizontal distance the catapult launched the tennis ball.
Length of Catapult Arm (cm) Horizontal Distance (cm)
60 320
80 352.4
100 386.8
60 288.1
70 315
75 322
90 362
100 390
85 350
