Theoretical Range: Range = 2* h * (M/m)
                                       = 2 * (0.64 m) * (18.18 kg/ 0.057 kg)
                                       = 408.25 m
The differences between our theoretical range, 408.25 m, and our average on test day, 23.74 m, is quite great. It is a difference of 384. 51 m. I believe that there are many reasons why our trebuchet did not meet our theoretical range, they could be air resistance, the pouch not being perfectly efficient, friction on the throwing arm, the tennis ball not being ideal for being the object thrown by a trebuchet and release angle.
