Uniform Circular Motion: Practice Problem & Solution

The angular velocity of earth about its axis of rotation is :
2π/(60×60×24) rad/sec
2π/(60×60) rad/sec
2π/60 rad/sec
2π/(365×24×60×60) rad/sec

Solution Explained:

To solve this problem, we apply the core principles of Uniform Circular Motion. Understanding the underlying formula is key to arriving at the correct answer below:

Angular speed ω = 2π / T = 2π / (60×60×24) rad /sec
