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 man jumps out from an aeroplane. As the man falls, he opens his parachute. What is the man’s terminal velocity if his drag coefficient with his parachute is 0.55, the combined mass of the man-parachute system is 80 kg, the surface area of the man and his parachute is 10 m^2 , and air density is 1.225 kg/m^3 . If a human can survive up to 13 m/s impact speed on a hard floor, can the parachuting man survive...

Water is moving with a speed of 20.0 m/s through a pipe with a cross-sectional area of 3.0 cm2. The water gradually descends 20.0 m as the pipe's cross section increases by a factor of three. What is the speed of flow at the lower level? How much higher is the pressure at the lower level compared to the upper level?
