Physics 173 Internet
Question of the Week
May 18 - May 22, 1998
This week's Internet search question of the week pertains to the
topic of roller coasters. Use a major search engine
Dogpile, etc.) to find a site
titled Roller Coaster Physics by Tony Wayne. (If you still cannot
find the page, you will likely find a link from a GBS page - visit
the Project Corner, click Year-End Projects, click on the Physics
of Roller Coasters, click on a page full of WWW links, and
look for the Physics of Roller Coasters link.) This site is
written by a high school physics teacher for high school physics
students; it details the physics of roller coaster rides.
Once you have found the site, do the
following (1.5 pt.):
- Identify the URL (address) of the page.
- Describe the search path which you took to find the page
(see example description).
- Navigate to the page titled "Hills and Dips" and answer the
- Explain the connection between the experience
of riders along roller coaster hills and projectile motion.
- In your own words, summarize the effects of a roller
coaster hill's shape upon the feelings of weightlessness
experienced by its riders.
An 80.0-kg physics student starts at a
height of 38.0-meters and cruises over the crest of a 12.0-meter
high hill. If the
of the hill is approximated at 58.0 meters, then determine the
speed and acceleration of the riders at the crest of the hill.
(Assume negligible air resistance.) Construct a free body
diagram of the rider at the crest of the hill (label the forces
according to type) and calculate the magnitude of each individual
force. (1.5 pt.) PSAYW
