Answer #1

Hey there!

The drag force can be given with

Fd = 1/2 ρ v2 A cd

where

Fd = drag force (N)

cd = drag coefficient

ρ = density of fluid (0.932 kg/m3)

v = terminal velocity (60 m/s)

A = projected area (0.33 m2)

Hence the drag coefficient Cdis

(The value of Fd 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 :)

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...

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.

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.)...

To measure her speed, a skydiver carries a buzzer emitting a steady tone at 1 800 Hz. A friend on the ground at the landing site directly below listens to the amplified sound he receives. Assume the air is calm and the speed of sound is independent of altitude. While the skydiver is falling at terminal speed, her friend on the ground receives waves of frequency 2 260 Hz. (Use 343 m/s as the speed of sound.) (a) What is...
