Explain why it is helpful to understand the different types of reactions, the Law of Conservation of Mass, and the way energy is involved in chemical reactions.

Amachine, modeled as a simple spring-mass system, oscillates in simple harmonic motion. its acceleration is measured to have an amplitude of 5,000 mm/s with a fre- quency of 10 hz. compute the maximum displacement the machine undergoes during this oscillation.
