What drag coefficient is needed to limit a 2m by 3m board and rider weighing 200 N to 10 m/s if he is free falling off a cliff.

Homework Answers

Answer #1

FD = Drag Force = mg = weight = 200 N

V= 10 m/s = velocity

A = area = (2m)*(3 m)= 6 m2

   = air density

We know the drag force formula

..................................(1)

Where C Is drag coefficient

  Drag coefficient is needed to limit =0.54

ANSWER = 0.54

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...
