Try this first
If a mass-spring system oscillates with a period of 1.5 seconds, what is the angular frequency?.
- A.4.19 rad/s
- B.2.09 rad/s
- C.1.05 rad/s
- D.6.28 rad/s
Model answer
What a good answer should say
- 4.19 rad/s
Explanation
Why this works
The angular frequency (ω) is calculated using the formula ω = 2π/T. Substituting T = 1.5 s gives ω = 2π/1.5 = 4.19 rad/s, indicating how quickly the system oscillates.
