document in order to edit. Using Excel: Calculate an average
Copy and paste your data into a blank Excel document
(I suggest using column B so you can put your labels in column A)
Place your cursor into a blank cell
Type the command =average(B2:B?) Where
“?” represents the last row your data is in… in this case it would be 12
Hit enter and there you go Using Excel: Calculate Standard Deviation
Same procedure as the average calculation except
use the command =stdev(B2:B?)

The general
form for the equation is this. Solve for
“n” using the log of slope
from
the line of best fit from the logarithmic graph. Remember to use only points
that appear on the line of best fit. Solve for “a”
by substituting into using your value of “n” and any value for and that is found
on the line of best fit. The actual formula is
defined as. Therefore the actual value for a = and n =0.5

Donald Trump is playing tennis on a rooftop
tennis court on one of his many buildings in New York. Surrounding the court is a 7.0m tall fence.
As a result of the most recent financial crisis, he is off his game and hits
the return on the serve a little harder than expected. The ball just clears the top of the fence
and heads for another building across the street. If Trump is 12 m from the fence determine: a) The initial
launch velocity (including angle) of the ball assuming he hits the ball when
it is 1.0m above the ground. (clue: find your x and y components of the
velocity first) b)
What floor of the building across the street does
the tennis ball hit if the buildings are separated by 70m, the fence on
Trump’s rooftop is 10m from the edge, and Trumps court is located on the 60^{th}

Using the low

energy loss of mass 2 The
lowfriction dynamics car was placed on the elevated airtrack. a small mass
was attached to the car via a light string and the string was feed through
the pulley. The air track
was engaged and the dynamics car was allowed to accelerate up the air track. Using a stop watch,
a metre stick, and the track markings the total height change, distance
traveled, and time were recorded. The final
velocity of the system was determined and used to calculate the final Ek. The total
energy change for mass 1 and mass 2 were calculated and compared. As a class,
the discrepancies between the differences in the values were discussed and
possible improvements to the investigation’s procedure were considered.
