Ruler with clay collision

Ruler with clay collision

Introduction:

In this lab we let the meter stick collision with the clay and see how high it go and calculate it find if they have the same result

Calculation:

we capture the video and find the final height is 0.08m

We do calculate like this 

we do it by part 

first we find the speed when it just hit the clay

then want though the momentum calculation as the figure

We came so far then we get the final high is 0.108m

Conclusion:

the experiment height is 0.08m

the calculation high is 0.108m

we have an error about 25%

It is quite different, but we can say that there might be lots of friction between the clay and the supporting stick. 

I think the result is reasonable.
