Hello!
I'm trying to enter a physics contest with my college and it is based on launching a junior baseball ("t-ball" 145g and aprox 5.7cm diameter).
I have to be able to transport it so I am considering using a design similar to the bullpup slingshot with the bands wrapping around pulleys to increase draw length.
I was trying to use the theraband calculator and estimated the weight is similar to a 35mm steel ball, but the ball I'm launching is much larger. I want max power, because there is a distance component to the contest as well as accuracy. I was wondering if there is a standard ratio for the taper used to increase power, and if I need to increase the band width or length to launch a larger diameter ball?
My team and I are trying to reach 150 meters for the launch distance.
I appreciate any and all help,
