Homework Statement
Brief:
Using the following:
1 ruler or stick, 1 tape measure, 1 ball of string, 1 timer, 1 calculator (+anything else you think you need)
Create an experiment which you will measure the rotational velocity of the earth.
Initially what you must do is measure the time it takes for a shadow to move over the ground using a ruler/stick and the timer. You will need to measure the length of the arc produced and the time it took to do this.
From this you will need to work out the velocity of the shadow.
The Attempt at a Solution
I am confused of what measurements to take regarding the arc of the shadow produced, and the equation for angular/rotational velocity.
Please help!
Ps. Sorry if wrong board.
