Calculating Terminal Velocity of Wooden Sphere

Click For Summary
SUMMARY

The terminal velocity of a wooden sphere with a radius of 0.18 m and a density of 801 kg/m³ is calculated to be 3.07 m/s under standard conditions. The discussion highlights the need to consider air density, which is 1.2 kg/m³, in determining the sphere's falling speed through the air. Participants emphasize the relationship between the sphere's density and the air density to derive a new drag coefficient for accurate terminal velocity calculations.

PREREQUISITES
  • Understanding of terminal velocity concepts

Given: wooden sphere

gravity = 9.8 m/s^2
radius of sphere = .18 m
density of sphere = 801 kg/m^3
Drag coefficient = 0.5

I found out the velocity of the wooden ball to be 3.07 m/s (please confirm).
Now it has to go through the air that has density of 1.2 kg/m^3.
What would be the speed of the sphere falling through this air desity?

That's where I'm stuck at. Could anyone expand on how the air density that the ball has to go through is related to the ball's density?

Basically you want to find a new drag co-efficient.
