Unformatted text preview: 100 200 300 400 500105 5 10 Displacement (cm) Time (s) a)What is the frequency f of the oscillation? (a)0.5 Hz, (b) 0.6Hz, (c)0.05Hz, (d) 0.06Hz 100 200 300 400 500105 5 10 Displacement (cm) b) What is the time constant τ ? Worksheet BONUS A 350 g block hangs from a spring with constant k = 23 N/m. The block is pulled down 5.5 cm from equilibrium, then released. a) Where is the block 1.5 s later (neglect damping)? b) What is its speed at t = 1.5 s (neglect damping)? c) BONUS: If the block loses half of its initial energy in 3.5 minutes, what is the damping constant of the system? d) How does the oscillation period compare for the undamped (T0) and the damped system (T)? (a) T< T0 (b) T>T0 (c) T=T0 (d) Not enough information....
