Find G: Physics Lab Experiment w/ 50 g Masses & Stop-Clock

[leviathanX777]

1. I have a to do a lab this week myself, it's not an exam more of assessing if I can do it or not. Here's what I have;

1. a set of six calibrated 50 g masses,
2. a stand with scale graduated in cm,
3. a spring with attached holder for calibrated masses,
4. a stop-clock.

I have to find G, the acceleration due to gravity.
2. W=mg
3. I have no attempt, just need to know a brief method of doing this experiment.

Thank you

Also I was thinking of using simple harmoic motion, Such as the equation s=-w^2s ? And perhaps the equation s=-kx for the extension of the spring? Reply soon because it's on Thursday and I really need help. Thanks.

You could use the mass-spring oscillator to find the spring constant (measure period).
Then you attach various masses and find the weights (from spring extension).
