Homework Statement
Determine the angular momentum of the Earth about its rotation axis (assume the Earth is a uniform sphere).
Homework Equations
L = Iω
I = (2/5)Mr^2
ω = 2\pi/T
The Attempt at a Solution
I = (2/5)(6.0 X 10^24 kg)(6.4 X 10^6m)^2
ω = 1.992 X 10^-7 rad/sec
L =...
Homework Statement
What is the angular momentum of a 0.210-kg ball rotating on the end of a thin string in a circle of radius 1.35m at an angular speed of 10.4 rad/s?
Homework Equations
I am using L = Iω
The Attempt at a Solution
I put I = (2/5)(0.210 kg)(1.35m)^2
ω = 10.4 rad /...
