Answer:
61.62 N/m
Explanation:
Applying,
1/F = 2π[tex]\sqrt{m/k}[/tex].................. Equation 1
Where F = frequency, m = mass of the spring, k = spring constant, π = pie.
make k the subject of the equation
k = m(2πF)²............... Equation 2
From the question,
Given: m = 1.00 kg, F = 1.25 Hz
Constant: π = 3.14
Substitute these values into equation 2
k = 1(2×3.14×1.25)²
k = 61.62 N/m
