An object undergoes simple harmonic motion along the x-axis with a period of 0.5 s and an amplitude of 25 mm. Its position is x = 14 mm when t = 0 and it is heading in the -x-direction (negative). In your logbook write an equation of motion with all the variables identified and sketch a graph of position vs. time for the oscillator. What is the initial phase? [Work in rotational coordinates to 2 s.f. and enter nothing at all for the units.]
