Question

Scenario #2: Up In The Air The scenario is all about different ways to travel while airborne.

Part A: Parachute A 100-kg skydiver is falling at terminal velocity with their parachute deployed as depicted in the simplified diagram on the right. The canopy of the parachute is attached to the skydiver’s harness by two strong cables, each pointing 25º out from vertical as shown. What is the tension in each cable?

Part B: Hot Air Balloon A hot air balloon has a volume of 2,000 m 3 . The air inside the balloon has a density of 0.75 kg/m3 , while the air outside of the balloon has a density of 1 kg/m3 . How much total mass can this balloon lift? (This mass includes that of the balloon fabric, basket, and any people hitching a ride.)

Part C: Bungee Jumping A typical bungee cord is actually made of 6 strands, each with a tensile strength of 16,000,000 N/m2 (1.6x107 N/m2 ) and a circular cross section with a radius of 8 mm. What is the maximum tension this bungee cord can withstand before it breaks?

Part D: Rocket The RIM-7 Sea Sparrow is a short-range surface-to-air missile, with a mass of 230 kg. Ignoring air drag, what is the minimum energy required to launch this missile to a height of 1,000 m?
