Open the simulation (https://phet.colorado.edu/en/simulation/masses-and-springst). Run the simulation and select Intro. Set the Spring Constant to the third line: Hang the block of mass 100 g to the spring on the left and measure the period of oscillation T using the stop watch located on the right of the screen (drag the stop watch outside its box). It might be easier if Slow speed is selected. Repeat ten times your measurements of the period and record your data. 11. What is average value of T? 12. What is the standard deviation of T? 13. Use your average value of T and Eq. (3) to find the spring constant k (N/m) F = −k x and ω = √ k m , and T = 2 π√ m k were the formulas given If you copy and paste the link, you should be able to do the simulation
