Question: What is the angular momentum of a 2 kg object moving in a circle of radius 3 m at a speed of 4 m/s?
Options:
24 kg·m²/s
12 kg·m²/s
6 kg·m²/s
8 kg·m²/s
Correct Answer: 24 kg·m²/s
Solution:
Angular momentum L = mvr = 2 kg × 4 m/s × 3 m = 24 kg·m²/s.

Questions & Step-by-Step Solutions
What is the angular momentum of a 2 kg object moving in a circle of radius 3 m at a speed of 4 m/s?
Angular Momentum – Angular momentum is a measure of the rotational motion of an object, calculated as the product of mass, velocity, and radius from the axis of rotation.
Circular Motion – The question involves an object moving in a circular path, which is essential for applying the angular momentum formula.
