Hello people. Try to think of an experiment to measure the value of g(acceleration due to gravity) using a soccer ball and other materials. State all your assumptions and describe the use of any apparatus.

All you need is to drop a soccer ball of a measured height, time the descent from the release to hitting the ground, and then record the value. Rinse and repeat ~20 times, and then there's your value.
You don't need to worry about reaction times, as your reaction time is a negligible error when you take reaction times of both the ball release and the ball hitting the ground with ~0.05 seconds maximum difference (unless you're drunk/stoned when doing this ;))
You could also try to make one giant pendulum with a soccer ball (assuming no friction, perfect point mass, no errors from the string), but I forget exactly how to do that.
