SHM & Masses on Springs

1. What is the time period when m = 2.00 kg and k = 300 N m-1?

[2]

T = 2π √(2.00/300) = 0.513 s (to 3.s.f.)

2. Find the mass when T = 10 s and k = 50 N m-1.

[2]

m = (T/2π)² * k = (10/2π)² * 50 = 126.6 = 130 kg (2.s.f.)

3. Find the spring constant when m = 4.0 kg and the frequency is 4.0 Hz.

[3]

T = 1/f = 1/4 = 0.25 s
k = m ÷ (T/2π)² = 2526.6 = 2500 N m^-1

4. Using T = 2π/ω (which you obviously know anyway), find ω to 2.s.f. when a mass-spring system has a mass of 6.0 kg and k = 3456 N m-1.

[3]

ω² = k/m,
k/m = 576,
√576 = 24 rad s^-1
