Question 1
A projectile is launched at an angle θ to the ground. Which of the following statements is
TRUE about the motion of the projectile? (Ignore air resistance.)
(A) Its acceleration is zero at its maximum height.
(B) Its horizontal velocity is zero at its maximum height.
(C) Its vertical velocity is zero at its maximum height.
(D) Its acceleration along its upward path is opposite in direction to its acceleration along
its downward path.
(E) Its horizontal acceleration is uniform and nonzero
please help me this is due soon :-((
please help me this is due soon :-((
We need to know the elevation, y, through which the glider falls. Show that for small angles, θ
, the elevation, y, is given by:
y = DH/L
where D, H, and L are defined on the figure.
sorry!
that is suppose to be: Fnet = √ (3*m*a)
yes it is absoulety right. :-( its one of my question from pre-lab for mechanics
thanks!:):):):):):):):):):)
We need to know the elevation, y, through which the glider falls. Show that for small angles, q, the elevation, y, is given by:
y = DH/L
where D, H, and L are defined on the figure:)
1. In the Newton's Law lab you are asked to perform an experiment and plot some data. Suppose the 'Correct' form of Newton's Law were:
Fnet = Ö3*m*a
and the mass of the system were 2 kg.
What slope would be obtained when the data are plotted as described in the write-up? ______________
2.
Suppose your lab has twelve groups and nine of them find that the Newton's Law theory and experimental results agree within the Standard Error of the Mean (SEM).
Would it be your judgment that:
*
all the lab groups were reasonably careful ___________?
or
*
some of the lab groups were sloppy in performing the experiment ______________?
Suppose we have some (x,y) data and analyze it using the Excel linest() function. The data is expected to fit the theoretical relationship:
Y = K1*X + K2,
where K1 is theoretically expected to have the value 0.75 and K2 is expected to have the value 0.50.
Upon analysis of the data, the linest() function returns the following result:
0.66 0.70
0.10 0.15
0.95 0.26
What is the experimentally determined value of the slope returned by linest? ______________________
What is the experimentally determined value of the intercept returned by linest? ____________________
Do theory and experiment agree for K1? ________________
Do theory and experiment agree for K2? ________________
thankss!
thanks!
thanks guys!

Place your answers in an Excel document and upload your file to the Class Grades assignment on Oncourse.
Below are grades for my class:
Grade Summer 03 Fall 03 Spring 04
A 12 7 12
B 15 4 11
C 6 4 6
D 4 0 6
F 4 7 5
Create the following charts on a single worksheet (be sure to rename the worksheets to something meaningful):
A single pie chart using the total number of letter grades for all three semesters.
A single bar chart displaying the above data. There should be 3 bars (one for each semester) for each grade for a total of 15 bars.
may God bless u with all happiness Franklin...
thanks for u r time man.
You need to create an Excel document that will start with a beginning checking balance of $1000. It will then need to add or subtract from this balance like a checkbook. The checkbook should be designed is such a way that it doesn't matter what the amount is or if it is a credit or debit. The balance should be correct if one enters +$100 or -$100 for a line. Please use these sample checks and deposits to enter into your checkbook:
January 2, Deposit $400
January 3, Check $39.72
January 8, Check $14.14
January 10, Check $19.19
January 10, Deposit $30
January 14, Check $125.72
January 16, Deposit $45.72
January 17, Check $50.77
January 20, Check $220.15
In addition to the above requirements, your project also needs to fulfill the following items:
Create a workbook containing exactly one worksheet. Name this worksheet "Checkbook". You need to delete any other worksheets present.
Format the worksheet using at least 3 different font colors and 3 different background colors.
You need to use at least one relative reference and at least one absolute reference in your formulas.
Save your Excel workbook and upload it to the Checkbook assignment on Oncourse.
