Question

Determine the drag coefficient of a 75kg skydiver with a projected area of 0.33m^2 and a terminal velocity of 60 m/s. Air density at the skydiver's altitude is 0.932 kg/m^3.

Answer #1

Hey there!

The drag force can be given with

*F _{d} = 1/2 ρ v^{2} A
c_{d}*

*where*

*F _{d}*

*c _{d}*

*ρ* *= density of fluid (0.932
kg/m ^{3})*

*v* *= terminal velocity (60 m/s)*

*A* *= projected area (0.33 m ^{2})*

Hence the drag coefficient **C _{d}**is

(The value of **F _{d} is taken as "mg" since the
acceleration value is not specifically mentioned here for the
drag**)

Hence

**is
the drag Coefficient**

*I hope the solution helps... Feel free to comment and
discuss further.... Cheers :)*

A skydiver with mass m = 50.0 kg has reached a terminal velocity
of 20.0 m/s. The skydiver's drag coefficient is:

Why does deploying a parachute slow down a skydiver?
A. Parachutes provide air drag. Once the parachute was deployed
the resulting air drag caused the skydiver to actually start going
upwards. So in fact, the skydiver doesn't slow down but starts
traveling upwards until gravity overcomes the air drag and brings
the skydiver safely to the ground. This is why the skydiver slows
down.
B. At the moment the parachute is deployed the skydiver is
moving fast. The high speed...

An Airbus A320 has a total wing surface area of 122.6m^2 and a
drag coefficient of 0.0872. In cruise, the aircraft files at 840
km/s (233m/s) at an altitude of 10,000m where the air density is
0.4135 kg/m^3. If the max engine is 100 kN engine, what percentage
of that thrust is the pilot going to be using in cruise?
*A380 has 2 engines

Determine the terminal velocity of a 90 kg skydiver. How long
will it take to reach that velocity? Typical drag coefficient and
the frontal area of skydivers are 0.1 and 0.15 m2 ,
respectively.

A 60.0-kg and a 90.0-kg skydiver jump from an airplane at an
altitude of 6.00*10^3 , both falling in the pike position. Make
some assumption on their frontal areas and calculate their terminal
velocities. How long will it take for each skydiver to reach the
ground (assuming the time to reach terminal velocity is small)?
Assume all values are accurate to three significant digits. Use
Drag Coefficient 1.21kg/m^3 and frontal Arear of skydiver of
0.140m^2.

The mass of a bicyclist and bike is 80 kg. The drag coefficient
is 0.79. Frontal area is 0.42 m^2. The density of air is 1.1 kg/m^3
at this elevation. The terminal velocity is reached when the drag
force of a free falling object is equal to the weight.
a)Estimate the magnitude of the terminal velocity of the cyclist
after he has ridden his bike off of a cliff. Assume that the
frontal area remains constant during the fall.
b)Estimate...

Consider a skydiver of mass 75 kg who jumps from an airplane
flying at an altitude of 1,900 m. With her parachute open, her
terminal velocity is 8.1 m/s.
(a) What is the work done by gravity?
J
(b) What is the average force of air drag during the course of her
jump? (Enter the magnitude of the force.)
N

A skydiver is at an altitude of 1,525 m. After 11.0 seconds of
free fall, he opens his parachute and finds that the air
resistance, FD, is given by the formula
FD = −bv, where b is a
constant and v is the velocity. If b = 100,and
the mass of the skydiver is 86.0 kg, first set up differential
equations for the velocity and the position, and then find the
following. (Assume air resistance is negligible prior to the...

A 510-g squirrel with a surface area of 905 cm2 falls from a
4.4-m tree to the ground. Estimate its terminal velocity. (Use the
drag coefficient for a horizontal skydiver. Assume that the
squirrel can be approximated as a rectangular prism with
cross-sectional area of width 11.4 cm and length 22.8 cm. Note, the
squirrel may not reach terminal velocity by the time it hits the
ground. Give the squirrel's terminal velocity, not it's velocity as
it hits the ground.)...

A bicycle rider has a drag area of 0.22 m2. She is riding at a
velocity of 8.3 m/s along the road and the air density is 1.2
kg/m3. Total mass of the rider and bike is 93 kg. The coefficient
of rolling resistance is 0.004. She is riding into a headwind with
velocity 1.8 m/s. The road is horizontal. What power (watts) must
the cyclist produce to maintain the speed of 8.3 m/s?
