James Bond leaps without a parachute from a burning airplane flying at 15,000 ft. Seconds later, his assistant, who was following behind in another plane, dives after him wearing her parachute and clinging to one for her hero. Is it possible for her to catch up with Bond and save him?
Yes, because whereas Bond has no parachute, his assistant has two and will have a higher mass.
Yes, because Bond can orient himself horizontally and spread his limbs to increase drag, and his assistant can orient herself vertically and streamline her profile to reduce drag. No, because once an object reaches terminal speed, the force of gravity and the drag force cancel, and therefore there is no way to change the terminal speed of the object without an additional external force.
No, because the acceleration due to gravity ? is the same for all objects near Earth regardless of the mass and shape of the falling object.
Yes because bond can orient horizontally and spread his limbs to increase drag which will slow him down while his assistant can orient herself vertically to reduce drag and increase her speed.

An airplane pilot fell 340 m after jumping from an aircraft without his parachute opening. He landed in a snowbank, creating a crater 1.30 m deep, but survived with only minor injuries. a) Assuming the pilot's mass was 94.0 kg and his terminal velocity was 45.0 m/s , estimate the work done by the snow in bringing him to rest. Model him as a particle. b) Estimate the average force exerted on him by the snow to stop him. c)...
