Part 3: Geometry/Trigonometry
(For Physics, make sure your calculator is set in degrees)
Frequently in Physics and Astronomy we must represent angular measurements in the form of degrees, arcminutes and arcseconds, rather than decimal degrees. Your TI-8x calculator can actually perform this function listed under catalog (above the zero). 23.569875 degrees can be converted to degrees-minutes-seconds under the catalog function as >DMS to become 23o 34' 11.55", read as 23 degrees, 34 arcminutes, 11.55 arcseconds. This can also be done by hand, whereas, there are 60 arcminutes in 1 degree, and 60 arcseconds in 1 arc minute or 3600 arcseconds in 1 degree.
Use your calculator converter under catalog to convert the following decimal degrees to degrees-minutes-seconds
11. 18.563248o
12. 125.32657o
13. 168.523658o
14. 255.325684o
15. 53.56987o
Part 4: Word Problems
speed = (distance / time) or speed x time = distance, speed is a "rate"

16. At 10:00 am two planes leave an airport. If the northbound plane flies at 280 mph
(miles per hour), and the southbound
plane flies at 320 mph, at what time will
they be 1000 miles apart? (DBW, p66,
#16)
17. A boy leaves on a bicycle trip at a speed of
8 mph. One hour after departure, his
father, realizing that his son
forgot some camping gear, sets out by car.
How
fast must the father drive to
overtake the boy in 15 minutes? (Assume
constant
velocity, neglecting any time for
acceleration/deceleration) (DBW, p66, #17)
18. Davis made a car trip in 3 hours, while the
return trip took 3.5 hours. If his speed
going was 5mph more than his speed
returning, how many miles was the total or round
trip? (DBW, p67, #20)
19. If Jane were able to increase her cycling
speed by 4mph, she would be able to
cover
in 2 hours a distance that now takes her
3 hours. What is the best speed
she
achieves at present? (DBW, p67, #28)
20. A "local" train leaves a station
and runs at an average of 35 mph . An
hour and a
half later, an "express"
train leaves the station and travels at an average speed
of 56 mph on a parallel track. How many hours after it starts will the
"express"
train overtake the "local"
train? (DBW p75, #44)
