1. A spring oscillates for 4 seconds and does 3 complete cycles. What is its period?

2. A spring oscillates at a rate of 4 cycles in 2 seconds. What is its rotational speed in rad/s?

3. A spring is oscillating with a 0.2 m amplitude. Assuming a radial speed of 31.0 rad/s and no phase difference from a full amplitude start, what is its position at 4 seconds? (Make sure the calculator is in radians mode.)
