Amplitude (x0)=5 cm

Find the spring constant and value of q

Solutions

Expert Solution

Given that :

amplitude, x₀ = 5 cm = 0.05 m

Total mass (in kg) : [(0.1) + (0.2) + (0.3) + (0.4)] kg

m = 1 kg

Total time-period squared (in s²) : [(0.2025) + (0.36) + (0.5625) + (0.81)] s²

T² = 1.93 s²

The spring constant which will be given as :

using an equation, T = 2m / k { eq.1 }

squaring on both sides, we get

T² = 4² (m / k)

k = 4² m / T² { eq.2 }

inserting the values in eq.2,

k = 4 (3.14)² (1 kg) / (1.93 s²)

k = (39.4 / 1.93) N/m

k = 20.4 N/m
