Few disabled can play
“It’s our belief, that it’s one of the best sports for people with disabilities…anyone with a disability.”
Bob Hope, East Amputee Golf Assoc

Feasibility: Beyond Foam
Energy Conservation
Spring PE = Golf Ball KE kθ2 = mv2
For 200 yd Launch: Torsion Springs w/ k = 35.3 N-m
Special order…but feasible

Take-A-Ways
Spring needs custom manufacturing
Destroyed Springs

Take-A-Ways
Release Mechanism needs force to keep pin in place
Rubber Bands

Future Consideration
Structurally Stable
Trajectory/Distance adjustments
Load Ball Automatically
Alternative Launching Mechanisms
