Spring Oscillations - Finding Unknown Mass 1) Purpose: finding the average of mass, in kg, of uknown mass. 2) Description of setup and method: for this lab we are utilizing a simulation to mimic life-like cirucmastance 3) Choice of color for unkown mass: red 4) Rearrange the formula for period T to isolate mass m: T = 2 pi sqrt(m/k) M=(KT2)/(4PI2) 5) Spring constant marking (ask your instructor): NOTE: For spring constant k, use the same setting and your result from lab 1. k (N/m)
