Homework #38 - Simple Harmonic Motion Handout Problems: 1. A mass-spring system is oscillating in the horizontal direction. If the mass is 0.25-kg, the spring constant is 12 N/m, and the amplitude is 0.15 m, then what will the total energy of the system be? 2. For the spring of problem 1, (a) what would be the maximum speed of the mass? (b) Where would this occur? 3. A 0.50 kg mass oscillates when attached to a spring with spring constant 200 N/m. What is the frequency of the oscillations? 4. How long should a pendulum be in order to have a period of exactly 1.0 second? 5. Two similar springs, each with the same length and a spring constant of 300 N/m are attached together in parallel. What will the spring constant of the combination be? What if they were connected in series instead
