Intro to Simple Harmonic Motion (Horizontal Springs) Video Lessons

Concept

Problem: A 0.600 kg block is attached to a spring with spring constant 15 N/m. While the block is sitting at rest, a student hits it with a hammer and almost instantaneously gives it a speed of 44 cm/s.(a) What is the amplitude of the subsequent oscillations? Answer should be in cm.(b) What is the block's speed at the point where x = 1/4 A? Answer should be in cm/s.
