Question

7. If friction is negligible then for any two locations Eq.4 in the lab manual can be written as PE, + KE'-PE2 +KE2 . Since y-0 at location 2, the equation then becomes 2 Plot a graph putting mv' in the y-axix and mgd in the x-axis using Excel. (Since you know d you can calculate mgd. Note also that mgd is not equal to mgh(PE)]. 125] According to the highlighted equation what should be the slope of your plot? . Draw trendline of the graph using Excel and display equation of the trendline. .Write down the slope of the trendline with its unit in the same graph. · Determine ? using the slope value in the same graph. 8. Explain what might be the reasons that the experimentally found inclined angle is off from the measured (using protractor) angle of inclination. 13] esperimantic

Explanation / Answer

The measured angle is off from the experimentally found angle because the least count of the protractor is one degree and it cannot measure angles with more precision.
