A mass oscillates on a horizontal spring in a simple harmonic motion. It is observed that the duration of one full oscillation cycle is 0.50 π seconds, and that the maximal displacement of the oscillator from the equilibrium is 12.0 cm. Let time instant taken as t = 0.00 sec correspond to the moment when the mass is at the location 10.0 cm to the left of the equilibrium, and moving to the left.

1. Find oscillator’s velocity and acceleration at t = 0.00 sec.

2. Obtain the equations for ?? (?) and ?? (?), making sure that numerical values for ?, ? and ?0 are substituted in. Show all relevant work in determining ?0.

Simple Harmonic Motion: Mass on Spring (Explanation of lab.) [ The intentions of this lab were to further our understanding of spring mass motion by creating a harmonic motion system to find values for spring force and oscillation periods. By the end of the experiment, our group was able to experimentally determine how the measure of spring constant, k, in a harmonic motion system depends upon oscillation periods and ??y. We began our finding of k by running the experiment...
