Two packages are dropped from an airplane. A parachute can increase the cross sectional area of each packages by a factor of 31. The parachute on package 1 fails to open, and the terminal speed of package 1 is 10 m/s. The parachute on package 2 opens. What is the terminal speed of package 2 in m/s? Enter a number with one digit after the decimal point.
Homework Answers
Using R = ½CρAv2
vterminal2 is proportional to 1/A, so
102 = 1/(A*31)
A = 1/3100
Then for package 2nd vterminal = sqrt(1/A) = sqrt(3100) = 55.7 m/s

John jumps out of an airplane at a height of 10,000 feet and opens his parachute. He quickly reaches a terminal velocity of 53 m/s. When he is 146 m above a hovering supply helicopter (and 500 m above ground), a supply package is dropped. The package is small enough that the air resistance is negligible. Will John reach the package? If not, how close does he come?

A water intake at a pump storage reservoir (the figure) has a cross-sectional area of 0.642 m. The water flows in at a speed of 0.480 m/s. At the generator building, at distance D = 119 m below the intake point, the cross-sectional area is smaller than at the intake and the water flows out at 9.67 m/s.
