A mass of attached to a horizontal ideal spring of spring constant oscillates in simple harmonic motion. What is the angular frequency of oscillation?
Answer and explanation
Correct answer: C.
- Step 1: State the relationship for simple harmonic motion angular frequency: .
- Step 2: Substitute the values (, ): .
- Step 3: Evaluate the square root: .
Answer
.
Why not the others: '' divides by after taking the square root; '' forgets the square root and divides by ; '' forgets the square root entirely ().
