Work done by air resistance

An air pilot fell 350 m after jumping from an aircraft without his parachute opening. He landed in a snow-bank, creating a crater 1.25 m deep, but survived with only minor injuries. Assuming that the pilot mass is 80 kg and his terminal velocity is 35 m/s, estimate work done on him by air resistance as he fell.

    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)...

    In February 1955, a paratrooper fell 370 m from an airplane without being able to open his chute but happened to land in snow, suffering only minor injuries. Assume that his speed at impact was 61 m/s (terminal speed), that his mass (including gear) was 68 kg, and that the magnitude of the force on him from the snow was at the survivable limit of 1.0 × 105 N. What are (a) the minimum depth of snow that would have...

    In World War II, there were several reported cases of airmen who jumped from their flaming airplanes with no parachute to escape certain death. Some fell about 21,161 feet (6450 m), and some of them survived, with few life threatening injuries. For these lucky pilots, the tree branches and snow drifts on the ground allowed their deceleration to be relatively small. If we assume that a pilot's speed upon impact was 116 mph (52 m/s), then what was his deceleration...

    3. On "The Simpsons," when Bart fires Mr. Burns as his father, Mr. Burns is dropped through his own trap door. When Mr. Smithers jumps after him, with what speed must he initially propel himself downward in order to reach the ground at the same time as Mr. Burns? Assume that Mr. Burns fell down the trap 2.5 seconds before Smithers jumped in and that the pit is 200-m deep (ignore air resistance)

    5) (10 pts) John is baby-sitting Casey, his 3-year old brother. He puts a crash helmet on Casey, places him in the red wagon and takes him on a stroll through the neighborhood. As John starts across the street, he exerts a 58 N forward force on the wagon. There is a 20 N resistance force (friction) and the wagon and Casey have a combined weight of 302 N. Construct a free body diagram showing all the forces acting upon...
