Q1. A 170 g block hangs from a spring with spring constant 9.0 N/m. At t=0 s the block is 24 cm below an equilibrium point and moving upward with a speed of 104 cm/s. What is the block's oscillation frequency? What is the block's distance from equilibrium while the speed is 21 cm/s? What is the block's position at t=1.0 s?
Q2. A stretched rubber band has the length of 0.04 m and a fundamental frequency of 462 Hz. What is the speed at which waves travel on the rubber band?
