Q
Q: If the moment of inertia of a body is 10 kg m², what is the angular momentum when it rotates with an angular velocity of 5 rad/s?
Solution:
Angular momentum L = Iω = 10 kg m² * 5 rad/s = 50 kg m²/s.
Steps: 5
Show Steps
Step 1: Identify the moment of inertia (I) of the body, which is given as 10 kg m².
Step 2: Identify the angular velocity (ω) of the body, which is given as 5 rad/s.
Step 3: Use the formula for angular momentum (L), which is L = I * ω.
Step 4: Substitute the values into the formula: L = 10 kg m² * 5 rad/s.
Step 5: Calculate the result: L = 50 kg m²/s.
