Prelab: Simple Harmonic Motion Square both sides of the equation above. If we plot vs. , what is the expression for the slope of this graph? 2. Using a spring attached to a vertical support, develop an experimental procedure to determine the spring constant for the spring hanging from the support using a spring, a set of weights with hangers. Your method shouldn't stretch the spring more than 5 cm. 3. If a mass m==500g is suspended from the end of a spring, its length is changed by 10 cm at the equilibrium. a. What is the spring constant k? b. What is the frequency f of the mass-spring system? 4. Below is a position vs time graph obtained from a mass- spring system using a motion sensor, Measure the amplitude A, period T, and frequency f from the graph (hints: Remember the definitions for A, T and f )
