PH220 Lab 2 Maximum Range of a
Projectile
Lab 2 (see textbook pages 54-64, Chapter 3 and especially Example 3-8,
p. 60) involves a projectile being fired upward at an angle to the
horizontal. You are to program the spreadsheet Excel (a similar
substitute software program is permissible) to determine the maximum
injection angle, that will result in the greatest downrange distance,
R. Assume m/s and g is approximated as . Fill in the data table, and
answers for the blanks and complete the graph (properly labeled and
annotated) in the Lab Answer Sheet at the end of this lab. {Hint: watch
out for conversion problems from radians to degrees in Excel}. Send in
this Lab Answer Sheet only when all of the labs are completed. These
can be sent via USPS (postal), or scanned and sent as a pdf or picture
files (e.g. .tif, .gif. etc.) or by any other method of your choice as long as
the answer Sheets are legible and translatable by Grantham University.
Access Excel. Your data table will look similar to that found for Lab 2
below. The injection angle, will go from 0 degrees to 90 degrees in
steps of two (2) degrees. Once you have the range formula programmed
for use the “fill down” option in Excel to “distribute” the solutions to
the other cells for the other angles. Include your completed full Excel
data table with your Lab Answer Sheet. Then graph the data in order to
construct a R. vs. graph. Denote on this graph, the maximum range, and
the angle, where this occurs. Be sure that your graph is properly
labeled. For Lab 2 return your Lab Answer Sheet with: (1) completed
Excel spreadsheet, and (2) graph of R vs.
