Problem:
To find the distance across a river, a surveyor chooses points A
and B, which are 197 ft apart on one side of the river. She then
chooses a reference point C on the opposite side of the river and
finds that A = 47° and B = 70°. Approximate the distance from A
to C.
а. 207 ft.
b. 217 ft.
c. 278 ft.
d. None of the given
A Porsche challenges a Honda to a 200-m race. Because the Porsche's acceleration of
3.5 m/s² is larger than the Honda's 3.0 m/s², the Honda gets a 1.0 s head start.
• The speed of light is 3*108 m/s (aka 300,000,000 meters per second). What is the speed of light in centimeters per second, kilameters per second, and
miles per hour? (Hint: there are roughly 1.6 km per mile and 3600 seconds per hour) Remember to show the math, Google can be used to check your
answer, but it is worth no credt without the work shown. If you are having a hard time explaining your math on the computer, you are also welcome to do
the work by hand and include a picture of the results.

- •11 For about 10 years after the French Revolution, the French government attempted to base measures of time on multiples of ten: One week consisted of 10 days, one day consisted of 10 hours, one hour consisted of 100 minutes, and one minute consisted of 100 seconds. What are the ratios of (a) the French decimal week to the standard week and (b) the French decimal second to the standard second?arrow_forwardIf you have spent much time driving, you probably have a good sense of speeds between about 10 and 70 miles per hour. But what are these in meters per second? What do we mean when we say that something is moving at 10 m/s? To get a better sense of what these values really mean, do some observations and calculations on your own: • calculate typical car speeds in meters per second • estimate jogging and walking speed by timing yourself; convert the measurements into both m/s and mi/h • determine the speed of an ant, snail, or falling leafarrow_forward• Part A To what potantiai should you charge a t0 F capacior to or 40 J ot enengy Express your answer using two significant figures VE AZ 810 Submit X Incorrect Try Again; 4 atemgte remaining siearrow_forward
