UNIT 9 WORKSHEET 2 Answer each of the following questions by writing all applicable equations and information, showing all work, and circling final answer with appropriate significant gures and units. 1 Fspring = 'kX f = E Tpendulum = ZHJE Tspring = 211% Part 1 Spring Oscillations: In each case, solve for the spring constant of the system in N / m. 1. A mass of 25.0 g is attached to a certain spring and completes 20.0 oscillations in 4.50 s. 2. A mass of 0.880 kg is attached to a spring and is set into simple harmonic motion with a frequency of 0.714 H2. Part 2: Simple Pendulum Oscillations 3. The reading on a metronome indicates the number of oscillations per minute. Calculate the frequency and period of the metronome's oscillation when the metronome is set to 215 oscillations per minute. 4. A trapeze artist suspended in air swings in simple harmonic motion with a period of 3.40 5. Calculate the length of one of the cables supporting the trapeze
