Question

A skydiver of mass m = 70 kg, which includes the mass of all the equipment she is wearing (helmet, parachute, etc.), jumps from an airplane at high altitude. The density of the air is ρ = 1.22 kg/m3 .

(a) Estimate a numerical value for the terminal speed of the diver while she is in a horizontal spread-eagle formation. (Parachute is not open.) The drag coefficient of the diver in this formation is about 1.0. Any other needed quantities should be estimated. Show your starting formulas and all your work.

(b) Estimate a numerical value for the terminal speed of the diver while she is in a head first vertical dive. (Parachute is not open.) The drag coefficient of the diver in this formation is about 0.70. Any other needed quantities should be estimated. Show your starting formulas and all your work.

(c) Estimate a numerical value for the terminal speed of the diver when her parachute is open. The drag coefficient of the diver in this formation is about 1.75. Any other needed quantities should be estimated. Show your starting formulas and all your work.

Answer #1

A mountain climber of mass m=75.0 kg slips during a climb and
begins to fall freely. She forgot her rope and had to use an ideal
spring. The spring is hanging vertically with an unstretched
equilibrium position at the origin, x=0. On her descent, she grabs
the end of the spring which has a spring constant of k= 981 N/m.
Ignore friction, air resistance, and any other dissipative
effects.
a) The climbers velocity when she grabbed the spring was 20.0...

Space X launches a rocket of mass m off the edge of a cliff of
height h . The rocket produces a constant thrust force of unknown
magnitude that is directed at an angle θ above the horizontal.
Unfortunately, the rocket crashes into the ground a distance d from
the base of the cliff. Determine the magnitude of the rocket’s
thrust force and the speed of the rocket when it crashed. You
should also include a graph of the position...

Based on the following:
The estimated purchase price for the equipment required to move
the operation in-house would be $500,000. Additional net working
capital to support production (in the form of cash used in
Inventory, AR net of AP) would be needed in the amount of $25,000
per year starting in year 0 and through all 5 years of the project
to support production.
The current spending on this component (i.e. annual spend pool)
is $875,000. The estimated cash flow...

Your corporation is faced with the decision of which Word
Processor to purchase for its manuscript typing pool (think
‘Mad Men’ here). It can buy the Hack brand
processor software package at an aggregate (multi-copy licenses)
up-front expense of $80,000, which would also require $20,000 in
annual year-by-year maintenance/upkeep expenses. Hack
initial cost would be depreciated on a straight-line basis to z
ZERO terminal book balue at the end of its four-year useful life.
This package’s software and supporting hardware...

Please answer all not understanding:
1. Volumetric expansion coefficients of simple materials are
often well catalogued. However, the thermal expansion coefficient β
of a human body is less well known. This could affect the human
body\'s specific gravity and, therefore, measurements of its
body/fat ratio. Suppose that a human body of weight w0 (on dry
land) is placed on a scale while completely immersed in
formaldehyde of temperature T1. Once the temperature increases by
ΔT, the scale reading drops by...

Melinda Baker had recently been transferred to the Home Security
Division of ADP. Shortly after taking over her new position as
controller, she was asked to develop the division’s predetermined
overhead rate for the upcoming year. The accuracy of the rate is
important because it is used all year long and any overapplied or
under- applied overhead is closed out to Cost of Goods Sold at the
end of the year. ADP uses direct labor-hours as the allocation base
for...

1) Jane is 25 years old and was able to save
$25,000. After doing some research, she
identifies a stock called HPG Industries that has a dividend yield
of 7% that has been consistent for the past 10 years. Based on this
information, she decides to invest in this stock. Considering that
HPG Industries pays the dividend consistently, how many years will
it take for Jane...
