3. The Empire State Building
1,250 ft Tall
Located on 5th Avenue
102 stories
Built in 1931
Featured in “King Kong”

4. Bungee Jumping Very Safe Longest Jump- 3,320 ft. Places to Jump-
Bridges
NOT Buildings

5. Bungee Cords

7. Force Diagram
Acceleration = Gravity - Acc due to Cord + Acc due to Drag
Acc due to Drag
Acc due to Cord
Jumper
Gravity

8. Equations Gravity= 9.8 m/s
Acc_due_to_Cord = if (Height-Cord_Length-Jumper_Height > 0) then(Stretch_of_Cord_k* ( Height - Cord_Length- Jumper_Height )/ Weight)
Air Resistance = Cd x R x V2/2 x A
Resistance = drag coefficient x air density x velocity squared / 2 x reference area

9. Verification and Validation
